I got an HTC touch diamond 18 months ago and hate it!
Battery even when new hardly lasted 24 hours.
Touchscreen inaccurate to the point of nearly unusable, even with stylus supplied, <i>slow</i> too, not even much good as a phone.
The MS sync app doesn't work consistently, so doesn't sync reliably with MS Outlook.
Final blow – I have an Orange email account, the phone was supplied by Orange, but no-one at Orange can tell me how to set it up to receive email from my domestic account.
The one redeeming feature for me has been a neat integrated GPS/Googlemaps app, whihc will hook up to satellites and plot where you are/want to go on GMaps. What a shame the rest of it wasn't as good!
Now- I'm not technical nor am I a phone buff, so I'm sure that someone with more skill could bludgeon the thing into submission. But that's not the point really is it? – why should I have to struggle and stress with something in today's 'plug and play' era.
For me anyway – HTC = horrid, tacky, compromised
