Well, I upgraded from a Hero to the Desire yesterday. It's all great apart from a few niggles, but one big one in particular.....I've lost half of my paid for apps I signed it to my Google account upon setting up the phone as normal. Everything seemed to work: Contacts and Calendar synchronised just fine, not so the Apps. The market seemed to recognise half of my paid apps, allowing me to download them for free again, but not the other half. I even did an App resore from my Hero using 'Mybackup' all to no avail. I'm still missing paid apps. They aren't even showing up in the Market any more, and if I download the free version and then try to upgrade it says there's no such App. Current paid for Apps that I'm missing and can't get back are: Weatherbug Elite MyBackup Pro Documents to go Full version Now I'm aware that there are some Market mismatches between Android 1.5 and 2.1 but I was under the impression that it was the 1.5 version that was missing out on Apps, not the other way round I'm posting this in both the Desire and Hero forums just to give people a potential 'heads up' in case they're in the same situation as me, or maybe someone will be able to tell me why half my paid for apps have gone after upgrading to 2.1 I've e-mailed the developers, so will wait to hear back.
