The rumors of google entering the mobile market been going around for a while. But now it doesn't seem like much of a rumor when htc says Yow its happening..
A few blatantly obvious things gonna happen for it.
Most of the Google web applications will probably be tied into it. such as
maps
personalized homepage
Google talk im / voip from the device it self
Google rss
and the long string of stuff you see at Google labs thinking about it.
The lovely thing about all this is they partnered with htc which probably means windows mobile at its core.. (which kinda weird when you think bout it. google making use of the Microsoft mobile operating system

).
wonder if htc is gonna start running a google mobile operating system.. and then decide how to push forward _base_d on the results of how it works?.
Would be lovely if google tried to use the Ubuntu mobile Edition to power it. and knowing how google likes to do things I wouldn't be surprised if this was linux _base_d mobile os over windows mobile.
