Objectively, the Samsung Galaxy S or iPhone 4 is probably a well rounded package than the HTC Desire HD. Our own comparison shows that. But personally, it is my favorite, all because of the 4.3-inch screen. After having used a older HTC HD 2, there is something to be said about a phone with a 4.3-inch screen. More real estate for your fingers and less squinting.
Abe Olandres said about this phone that:
The HTC Desire HD is definitely a great phone. It’s one of the best Android phone we’ve tested this year; actually, among the best smartphones we’ve used ever. It’s not a perfect phone; it’s got a few shortcomings too (yeah, that resolution was a bummer) but over-all, I’m pretty impressed with the handset. With a suggested retail price of Php35,000 it’s actually right within the range of all other flagship smartphones out there.
