I have been a Nokia user all my life and recently sitched over o HTC Touch. In fact I am currently writing this review from my HTC Touch.
Technical features: Latest version of windows. Version 6, 2 MP Camera, 1 GB card 9 Standard, decent battery life and a very sleek design. MS Office, Outlook Wi-Fi, MP3 ringtones, Windows media player.
Good: Design, size, weight.
Bad: Availability of accessories( like carrying case, holster), sound volume.is low but tolerable.
The battery lasts 2 days quite comfortable and to use the phone well is to use the phone to its full potential, get the GPRS activated and access your mails and outlook on the go.
Another feature that impressed me the most: You can create and modify MS Excel and MS Word documents in this and these same files are readable on the PC too. You can view but not create power point PPts. So create them on the PC transfer them via Bluetooth or USB and carry your docs wherever you go. Nokia does not have this. A very user friendly interface and the price is the best that can be. Approx 16000/-
By the way: HTC is the Original Equipment Manufacturer(OEM) for HP, IMATE, O2, DOPOD therefore any PDF Phone you use, you are using an HTC. Why use the higher priced other brand when you can get the real thing much cheaper.
PS: I watch MP4 movies on my HTC when I get bored in the office and my 2 GB Micro SD card lets me do it with wase.
