I have to disagree on the windows phone front, having had several they are unstable as a drunk man at sea. Iuse the E90 day to day, and yes i know its used to build houses, but its awesome.
the size means lovely web browsing, and enough screen space to view and edit all work documents, mail for exchange or blackberry connect (mail for exchange is better) gives me my email, calendar and contacts, a citrix program lets me remote access the server, and use it, rather than try to navigate round a desktop on a phone screen, and i'll not go on bout all the other great stuff. I also use a htc touch pro, and it is lame, even with registry tweaks.
More on topic however, if you tell your phone not to load/display html the site loads up in a lofi version, which is slightly harder to navigate, and not too much faster.
oh, and for all the iphone lovers this site sums it up perfectly, written by a genius
