I just got the O2 XDA Mini S also known as the I-Mate KJam/Qtek 9100/HTC Wizard/T-Mobile MDA. What can I say about this awesome phone. Its like carrying a mini laptop with you. The new windows mobile 5 platform is simply awesome. It comes with the familiar windows media player, and all other office software you are so familiar now. It has an internal memory or 128mb and a 64mb ram. Of course you can expand the memory by using the mini SD card. Carry music, movies anything... The reason I got this model is that it has a cool qwerty keyboard which slides out from the side. The screen automatically changes to horizontal mode. This for you to type longer documents, edit word, or excel files. You can even carry your power point presentations. The windows mobile 5 platform is relatively new so new programs are just about coming out, you wont be outdated with this phone for a long long time. It has all the other phone features that any other PDA phone has. WiFi is really nice, at the airport you can switch on and be on a high speed internet browse. Its not 3g, but then 3g has not really arrived in India. It has a cool 1.3 mega pixel camera. Takes videos in MP4, various resolutions are available. I think I have raved enough if you plan to buy a PDA phone then this it it. Look no further.
Imagine watching full length movies while waiting at the airport or on a boring train ride! Yes one can do that with this phone and more. Install a software and turn it into a webcam connected via Bluetooth to your system.
Update after installing new ROM
I now have the capability of Push Email, very much like the Black Berry, built into the new ROM. I receive email like I would SMS messages. How cool is that? No more running home/office to check mail check it right on your mobile! True Mobility.... ; )
