I have to dig around in subscreens to get to the apps I want - on the iPhone I just scroll left or right on the home screen, but on Android I only have six homescreen slots for apps, the other home screens are taken up with applets, mail and other shite, so I have to open the apps screen specifically, and then dig around in there.
Did you not try the phone out before you've bought it? Because you would have known that HTC Sense is like that.. You could have removed the Mail Widgets if it was getting in your way and long press the app in the app drawer to create shortcuts. RTFM. I have a HTC Desire and I prefer all the apps in the drawer instead of it cluttering the home screen. If you liked the iPhone way of organising things.. Try a Samsung, they pretty much copied iPhone's interface and hence getting in a legal battle with Apple.
The best laid plans of mice and men are held up in the legal department.
