I sell phones for a living, sales of this dwarf the iPhone now. The screen is bright and crystal clear.
The 1Ghz processor shines through brilliantly showing speed even with a few apps running in the background.
Messaging is perfect because HTC's dictionary is absolutely packed & you can have QWERTY, Mini-QWERTY or Alphanumeric keypads at your choice.
Some people don't like the looks but in real life it looks great and feels brilliant in your hand with a good weight and smooth feel with a mixture of aluminium and high-grade plastics.
Granted the Android Market isn't as packed as the Apple App Store but any iPhone user can tell you how much CRAP there is in the App Store. Android apps are a different breed and serve a purpose. And there's a higher percentage of free apps.
The camera takes a crystal snap, it's not on par with a Pixon or N86 or even the X10 but it will still impress your mates with the touch focus, face detection and direct web uploads.
The HTC invented Sense Interface is impressive and unbelievably customisable. You can put any app or widget on the home screen and use it instantly. Tons of wallpapers, brilliant colours, responsiveness and intuition on the phone make the user experience second to none.
I'm an iPhone user, but payday is next week and mine is in the back of my shop with my name on it.
My advice is this: if you want a brilliant smartphone and don't want the constrictions of an iPhone or the complicated interface of a BBerry then the Desire is you're next phone.
Simple, elegant & FAST.
