Best SE phone for e-mail and internet?

I currently have an SE k800i on Vodafone and my contract is up next month. 
Is there a better SE phone for e-mail and internet browsing? I like the
look 
of the new w890i. I know it's marketed as a music/walkman phone, but is it

any better than the k800i for e-mail & internet?

I want to change my phone anyway, as I don't like the k800i's joystick or 
un-configurable menu system. Do all SE phones have the same 
(un-configurable) menu system as the k800i?
