OK, I've had a chance to rest a bit after leaving at 2am to line up for the iPhone 5S release, and was fortunate to come away with a new phone!
As major news sites have reported, supplies are severely limited for this thing at launch, with internet sales being pushed out 7-21 days within hours of its availability.
At the AT&T store I picked again this year, supplies were very low. Silver and Gold versions, as well as the largest 64GB variants were not available at all.
New shipments should be coming in regularly from now on, but don't expect to walk into a store and find one this weekend.
So far I have been very impressed by the speed if the new A7 processor, and have had no problems with the fingerprint reader used to unlock the new phone.
Benchmark tests have been run by all of the major Tech blogs, with the most thorough testing as always done by anandtech. This phone is faster than any other phone on the market, easily blowing away the competition from the Android set, including the former leader, Samsung's international G IV.
If you already have an iPhone 5 you will notice the speed immediately, and if you are still using a 4 or 4S, run to the nearest store that has this phone in stock.
