Although there's an abundance of fantastic apps for the HTC EVO available in the Market and elsewhere, many software devs and companies still head to Apple's App Store first.

Most highly anticipated and desired apps will come eventually, though, so let's do something productive while we wait and share which ones we're looking forward to most. Whether there are public plans to make the apps or not, which ones do you want most on your EVO?
