I can kind of see where gadget007 is coming from.
I'm on my 3rd Windows mobile (C500, M2000 and now Vario).
The Vario is great, just the right size for data stuff (Push email, web browsing and sat nav), and only let down (IMO) by a slow processor, and flaky ROM's as supplied by T-Mob). An update to the I-mate version solved my issues quick enough, but it's not the best way to tempt the average mobile user over to the platform.
My last non Windows phone was a SE T610. I got it back from one of the offspring the other weekend saying it had broke. Removal of all the photos, and clearing of the txt folders soon got it working as it should again, but I kept it for a week and was reminded of how good it was at the basic stuff (phone calls, txts etc). It was also the best handset for synching with my Parrot car kit.
In an ideal world, I'd have a T-Mobile data only tariff for the Vario (why can't these be available to non-business users?) which I would use during the week when I'm away from home with no internet or personal e-mail access out of work hours.
But for the basics I'd have a phone like the K800i on a basic call & txt plan.
