Got mine in January, so figured shouldn't have any of the initial problems I'd guess. The main issue is the space on the phone. Runs out massively quickly due to apps updating and taking up more space and many can't be transferred to the SD due to either the phone not letting you (I know there's ways of getting round it) or the widget not working due to putting it on the SD (Mixzing music player being an example). Also, I think it possibly doesn't like the SD card I've bought as in Maps and a few other apps it'll throw up a problem with the card even though I've formatted via the phone and checked it with PC diagnostic tools.
Have to say though, that apart from that there's numerous things about the Desire that bug me. I hate the keyboard compared to the iPhone's - so imprecise in comparison. Miss the dedicated switch on the side for going to silent mode as well. It is little things, but I guess I'm needing weaned off the Apple cult and the Desire (so far at least) hasn't done it for me.
Shall maybe come back to it and root it in coming weeks to get to 2.3 and see how it goes. Just enjoying the Apple-y goodness the now lol
Oh and also, given my current status I'm loving the state of my bank account - healthiest it's ever been and the irony of that's not lost on me. Definitely won't last though :laugh:
