I already have an HTC mobile phone and it has always felt sturdier than others I have had such as Nokia and Samsung Tocco. This feeling of sturdiness carried over to when I tried both the HTC Desire and Samsung Galaxy S in the shop. I did end up plumping for the the Samsung Galaxy S. If you get over the fact that it feels a little flimsier, it is an absolutely superb phone. I think that the Desire was once voted the worlds most desireable phone (was it here I read that?) I can assure you that you would not be disappointed with either, just that I went for the Samsung (slightly bigger screen).
