I have an HTC TyTN from Vodafone I originally loathed it. However de-branding and putting the HTC Windows Mobile V6 on has made it much more stable so I tend to swear at it much less.
Like all 'do everything' phones it is a compromise.
What a I have realised, in using such a device, is the phone I really need has:-
3G for connecting another device (laptop or pda) to internet
Bluetooth for connecting headset and laptop pda
Fantastic voice control like orange wildfire.
fold out keyboard like a Nokia 6820 for texting
and a black and white e-ink display I can read in daylight that shows the time without me having to use a back light.
A 2.5mm stereo headphone / mic connector
and a standard mini/micro USB cable connector /charger.
Equally important I don't want to :-
browse the internet on my phone
read e-mail on my phone
take pictures /video with my phone
view anything in colour
listen to mp3's or radio.
Use a stylus on my phone
I used WAP once 5 years ago and have never sent or received an MMS
For mobile media / internet applications the Nokia tablets are great and paired with the phone I imagine would make me happy. If only they had coupled the latest tablet hardware with the psion MX 5 case and keyboard.
