I have the standard HTC Desire, had this since before the summer to replace a failed Acer Windows mobile phone. Love it! Apps, apps and more apps, open source development environment for when I get round to writing something more than an Android "Hello World" program! The API's seem very rich and easy to work with.
Only issue so far is that HTC Sync doesn't do Outlook notes or Onenote which is a pain, but when time allows, I'll code something myself if HTC don't get their act together.
