I will read that thread but just to say what i want
Speed:
Wifi:
GPS:
Multi emails
But whats top of the list is usability, I mean need to use it as a laptop booking appointments all the normal crap. Dont need or want fancy games and crap thats why i havnt looked at the Iphone.
Thats why i had the blackberry for the last 4 years cos it did what i wanted but tbh for the last 12mths it did nothing but cut me off and fall over.
Speed: About even,
just edged by the Galaxy S II, but close.
Wifi: Again, even. The Galaxy S II wifi can be a bit poor but the Sensation has some reported issues. Neither should worry you really though.
GPS: Even.
Multi emails: Even.
Usability: Sensation. It is quite a lot nicer out of the box and HTC Sense is certainly popular for this reason.
When you say 'I mean need to use it as a laptop booking appointments all the normal crap', can you clarify what you mean?
I'm assuming you need to book appointments with it, not literally use it as a laptop (like the Atrix can be used).
Just to add a few other points -
Battery life - Galaxy S II, but not a massive difference all round.
Camera/Video - Galaxy S II, but again, not a huge difference.
Screen - Galaxy S II but for the things you mentioned the slightly higher Sensation res may appeal to you.
Phone capability - About even.
As kona said, go and try them. As you don't know much about them just give them all a go and see which one jumps out at you.
