Okay, 2 min summary: More of a full function PDA with mobile phone capability than a mobile phone with extras...

Okay, feature list:
Integrated Camera, image viewer and photo gallery
Streaming video and video player for downloaded clips
MP3 player and polyphonic ring tones
MMS, text + pics and sound, e-mail with attachements and viewers
WAP and cHTML browsing
12Mb internal memory plus 16Mb on a memory stick (included)
Contacts with photos, calender and full PC synch
Bluetooth, infrared and USB
pJava and java CLDC/MIDP for addtional applications
I could spend ages explaining the features of this phone, and what it can do... basically, it can synch with your PC, you can upload apps and games (like Men in Black 2). It has a 'flip' keypad, which hides a full length colour touch screen..
The only problem is... if you want to call someone from your phone book, it'll take 2 mins to get through the menu system! (you have to select phone mode, then contacts, then contact list.. then you can call them)...
You will need to spend a week with the instruction manual next to the phone to use it properly..
It's a great peice of kit, dont get me wrong, but it is bulky (117 x 59 x 27 mm) not too heavy (158 g) and if you carry a PDA everywhere with you, then it is a perfect alternative..
I prefer the simplicity and configurability of the Nokia 7250...
Really, it's horses for courses..
