HTC Desire to Arc
I currently have the HTC Desire, so the Arc (which Will be in my hands tomorrow) (cant wait) looks like a big upgrade for me.
HTC desire vs Arc
1. More internal user memory (i only have 14mb free with everything on sd card that can be)
2. Camera quality better on the arc.
3. Photo taking much quicker on arc. & Physical Camera button (always the best)
4. Video sound quality Pathetic & tinny on the desire, sounds much better on the arc.
5. Faster processor even if it is a 1ghz processor.
6. battery on Desire lasts 17 hours on desire (hopefully a bit better on arc)
It all depends what phone you are moving from & what you want from a phone.
& remember the Arc has a LED notification light (even if in a silly place on the side) & NO Samsung does & if you have ever used a HTC or Motorola you will know how useful it is.
