After weeks of research, questions and indecision I finally bit the bullet and defected from my 2 year old iPhone 3G to the HTC Desire on O2 (UK). so far, i'm very impressed and pleased. I love my iPhone but fancied seeing things from the other side for 18 months. observations so far: 1. The battery life is similar to the iPhone 3G. 2. The screen is better, brighter, crisper (except in direct sunlight where it is a bit washed out as its oled). 3. The speaker isnt as good as the iPhone 3G's, a bit tinny but fine for calls, only notice it playing music, which i dont do very often without headphones. 4. I'm using double twist as an iTunes replacement and it seems ok. I'm finding apps via www.download.com and www.androidtapp.com and using barcode scanner to download them. 5. I couldnt export my iPhone contacts to SIM. So I exported my address book from windows 7 livemail as a .csv file. Then imported that into GMail on the pc. Then the Desire linked the Gmail contacts to the People app. 6. accesories and cases are very cheap compared to iPhone ones. I'll add more as I learn more great phone, loving android so far.
