Android phones, apps and tablets

I'll be upgrading my phone soon as my contract with orange is due for renewal, and wondering what would be a good upgrade from the HTC Tattoo. Been quite happy with the Tattoo actually, the only improvements I'd like is a slightly faster internet connection (processor?) and a slightly bigger screen. So I'm looking at the Desire and the Wildfire. Would I need to go to the Desire to get noticeably faster internet than the Tattoo, or would the Wildfire also be better?

Defintely skip the Wildfire if you want an upgrade from the Tattoo. The screen is small and the CPU is slower. Go with the Desire or the Desire HD.
