Awhile back I posted my take of the Sony Ericsson X10 mini and I indicated I would follow-up the review with its sibling the X10 mini pro.

I had high expectations for the X10 mini pro when I took it out of the box. My initial impressions on the physical aesthetics of the phone were justified. The X10 mini pro looks bulkier than its sibling but this is justified by the inclusion of a physical keyboard – with ‘real’ keys that you can touch and press.
Setting up the phone after a full reset (so I could clear any existing data settings by the previous user) was simple. This time I did not bother to look for a manual for the phone, instead I groped my way through the selection of menus, found what I needed, and kept on going.
Typing experience. Although this is a qwerty keyboard, some of the keys (numbers and special characters) have been moved around so it takes some getting use to it. When I first started typing I was concerned that my large thumb would make typing difficult. For the most part I was impressed that typing was easy EXCEPT when I was going for the E, R, T, Y keys as I always kept bumping into the edge of the display screen. The physical keys themselves need to be depressed with an effort to make the connection. I am not sure if this would change as you use the phone over time. But in my four days of using the phone, I found the effort to be unchanging.
In case you don’t feel the urge to slide out the keyboard, the T9 virtual keyboard is there for you. Personally I didn’t like my experience with the T9 keyboard, it kept interfering with my abbreviated SMS typing. I found it so annoying that I forced myself to slide out the keyboard each time I needed to send a text message. This can be a distraction if you are walking about town and you need to respond quickly to an incoming message.
More annoying, and I was unable to disable this function, is the appearance of the language bar on lower left hand corner of the tiny 2.55 inch screen. With so tiny a real estate, why did the engineers at Sony Ericsson keep this virtual button there. Did they think that a person typing a text would want to change language mid-entry? In fact this language bar quickly became a nuisance for me as it actually hampered my typing 50% of the time.
At 90×52 x17mm and weighing a mere 120g, the Sony Ericsson X10 mini pro is cute, distinctive and easy on the pocket. The 2.55 inch screen means the engineerings weren’t expecting owners of this phone to surf the web. Writing cryptic messages on Facebook or Twitting is not a problem but this is not the device for reading a full article from your favorite blogger or making a blog entry of your own, for that you really need a bigger screen.
I also didn’t notice it as much but watching a video from this phone quickly becomes impractical not because the screen is small but the reflective glass makes it hard to watch in a bright light setting (yes, even bright indoor lights).
As with its smaller sibling, the X10 mini, the pro has shortcut icons on the four corners of the screen. Changing these is easy. You can only have one widget per screen but that only makes sense since you have such a tiny screen. You can flick or swipe left or right to skim through these widgets.
If you Twit a lot or always want to know that’s happening in your Facebook account, Timescape streams these short messages with the avatar of the author lightly superimposed as a background for the message. Same goes for your sms messages.
Sony Ericsson phones are on par with the best multimedia gadgets out there. The X10 mini and X10 mini pro follow this tradition very well. The music player is excellent and despite the diminutive phone, you can still crank up the volume to hear it without headphones. (more…)

Mention ‘Smartphone’ and the products that come to mind are hand-sized devices about the size of your hand. Most weigh in excess of 180 grams. Most will show a bulge when placed inside your front jeans pocket, and I’d be very concerned about putting them on the back pocket.

The Sony Ericsson (SE) breaks this Smartphone tradition by coming in at a miniscule 83 x 50 x 16 mm. In fact the closest Smartphone rival of comparable capability is the larger and HTC Wildfire (106.8 x 60.4 x 12 mm).

Using the X10 mini can take getting used to. The UXP interface is an acquired taste (but don’t let my hesitation fool you, it doesn’t really take that much time to learn how to use the phone and most of its features).

WHAT I LIKE
In my view, four things combined to make this worth buying: (1) Android + UXP; (2) battery life in a small package; (3) reasonably good camera; and (4) size.

If you are a little overwhelmed by HTC Sense, you will likely appreciate the simplicity and capability of the UXP (UX platform). On the HTC Sense you can add widgets on each of seven home screens. But this is only possible because the phone’s display (say HTC Wildfire) is large enough to hold more than one widget. On the SE x10 mini, this is impossible given the 2.5″ (diagonal) display. But SE conceded this limitation by allowing you to post one widget on any of the 20 home pages. The one app per page actually minimizes the clutter I often find distressing as you start using the phone more frequently.

A phone of this size that supports 3G, GSM and Wi-Fi would surely conk out the battery even before eight hours is gone. SE continues its traditional of good battery life per charge with the X10 mini. I get about two days worth of calls, SMSes, emails via Wi-Fi, a few hours of music and one episode of a favorite TV series. The screen may look ridiculously small at 2.5″ but mind you I managed to comfortably watch a movie on the phone whilst I traverse the MTR stations in Hong Kong. No, I didn’t stay in the MTR station for the entire length of the movie. Instead I continue what I was watching each time I ride the train. All the HTC Android phones I tested don’t remember where I stopped the movie before stepping out of the train. As I result, I avoided using the phone. Yey, SE!

The SE X10 mini comes with a 5MP camera. I’ve tested the cameras on the HTC Desire, HTC Wildfire, and BlackBerry 8900, and I can tell you the X10 mini’s 5MP is a great little camera for taking shots outdoors. The photos are nice and crisp. You can’t this kind of quality from the other phones equipped with similar camera configs. SE also added a video light feature when you want to take videos with the phone.

While I carry a backpack everyday to work, I usually keep my phone in the front pocket of my jeans (left or right). With my trusty old BlackBerry 8900, its almost impossible to get the phone in, much less out of my jeans (I usually hold my breath and tuck my tummy in as I attempt to pull out the phone out of my pocket). The HTC Desire was just as tight. The HTC Wildfire was a little kinder to my pocket. The X10 mini fits in there and I can still cram a headset or a pack of tissue.
 

WHAT I DON’T LIKE
If there is anything to be learned from the Apple iPhone series is that simplicity of use is very important. Owners of Windows-based PCs, digital video cameras, digital cameras and DVD recorders don’t read the user manual that comes with their device. So it was for me that when I got the X10 mini to try out, I discovered that this is a complicated product to use. In fact I had to download the user manual from the Sony Ericsson website in order to learn enough about the phone to make practical use of it, like navigating using the UXP. Of course, once you get past the nuisances of the interface, everything else becomes simple.

Google Nexus One owners have likely upgraded to Android 2.1 or 2.2 by now. Some HTC phones are shipping with Android 2.1 with a few already earmarked for a 2.2 upgrade. Unfortunately for the X10 and X10 mini series, upgrade to 2.1 won’t come until the last quarter of 2010 (and likely it will be in the December timeframe). http://blogs.sonyericsson.com/products/2010/05/05/sony-ericsson-xperia%E2%84%A2-x10-to-get-uxp-upgrade-in-q4-2010/

I am not altogether sure why but after a week’s use I started to notice a lag when using the X10 mini. Whether its trying to switch on the phone to make a call, or send an SMS, or read my email, I notice a lag of a couple of seconds before the phone switches to the app I want to use. This is particularly annoying because Sony Ericsson has added a sensor that detects if the phone is next to your face, indicating that you making a call. What happens is the phone screen blanks out. I understand this is to make sure that you don’t accidentally press a button while on the phone. But if you need to quickly press a button (say if you are on an IVR call), the time it takes for the screen to come back up is very annoying).

MY FINAL THOUGHTS

I’m a long time SE handset customer for many years from my favorite T91 to my P810 and P900. I loved those phones. They worked as advertised and almost all cases I only have to take out the charger twice a week. This is a big difference compared to my wife’s experience with her Nokia phone. She’s a die hard Nokia customer despite the fact that (1) the Symbian interface lacks intelligence; and (2) the phones simply leak battery power big time.

Would I trade my BlackBerry 8900 for an X10 mini? Probably not! Why? I text a lot. I also read and respond to my emails on my BB. Nothing beats a physical keyboard for this kind of job.

I will be testing the X10 mini pro after this. Who knows? I just might change my mind.
