Just received my white 16gb posting this from it. This is the best phone I've ever bought I can't believe I was missing out all this time.
I agree with this ^^^^
I got an N95 just before the first gen iphone. Then I got the Omnia when the second gen/iphone 3g came out. But all along I was using hacks to run a simialr iphone style UI on both....family got two 8gb iphones last year and I said if they released a minimum 20gb model i would get it....so when this was announced I was glued tot he WWDC stream and pre-ordered my iphone two days later here in the UK and got it on the 19th.
I have never had a better phone which doubles as my laptop and COMPLETE media device.
Battery life after only 2 drain cycles went up to almost 8 hours of usage and 20+ hours between charges and about 6% battery of life left so not sure of other peoples issues. (see below for evidence)

I will jailbreak this in a few days once i see dev teams hack and lots more people post up results.
I am very satisfied...to say the least.
