In a nice little screen shot posted by @arnehess (from, we can see more apps populating the Windows Phone 7 Marketplace as expected.

While the ubiquitous "tip calculator" is there, the biggy appears to be a Google Voice app called 'GoVoice'. We're not sure if this a call-back method or one that auto-dials/logs in your Google account, but either way it's a good sign some of us will be able to continue using our Google Voice number when we get our new phone.
