HTC diamond or NOKIA 5800 help me decide with ur experience

HTC is a windows mobile phone where as the nokia 5800 is a symbian based phone. There are many applications made for both the phones, but I'd always choose a windows mobile phone over a symbian. What is the processor speed of the diamond, anything above 550mhz will never hang up.

velocity_186, If I have a choice here, I would still go for Nokia 5800. The HTC Diamond, though is new (relatively) and impressive being sleek, great display and even has 3D interface, is just disappointing to me when I tested it at one of the cellphone retail outlets. I just felt that the overall performance during my navigation in between the apps and even displaying of photo images to be a little bit sluggish. If you are the impatient me, where you just cannot tolerate a 2 seconds lapse, then this is not the phone for you. I suspect that there is a little over engineering here which is causing this sluggishness. The other issue with HTC Diamond is the battery life where I understand that if you are running the phone on full apps the battery standby time would not be true to its literature, so do watch out if you are a heavy user like one of my colleagues who has recently sold off his and went for another brand. Hope this will be helpful.
