Htc desire hd or iPhone 4?

HTC Desire HD is the better phone than iphone 4. i was facing the same problem before buying it a month back... i wanted to buy windows phone 7 (omnia 7) and also considered iphone 4, but when i had a look at HTC devices i was blown away. after few weeks of reviews and video's i bought htc desire hd and i am very satisfied with the device.....it's truly a smart phone.......
