I purchased mine on launch day from Best Buy. It has already replaced my laptop but there are a few bugs like someone here pointed out - If you put your device to sleep or just close the lid. Wake it up after about 2 minutes you will notice right away that the wireless connection status changes to limited which mean your not online anymore. The only way around this is to turn off your WiFi then turn it back on which is annoying. Otherwise it's the greatest thing ever!
I'm not actually getting this bug. What does happen with mine after waking it up is I get a momentary delay before the lockscreen slides up. Even trying to slide it up with a finger multiple times doesn't work. The delay is approximately 4 seconds or so.
Edit: There is also a delay of about the same time when I press the power button to turn the device off.
Edit 2: For some odd reason I decided to check for updates and there were a whole host of additional updates, 16 to be exact. Will install and report back on any noticeable fixes.
Edit 3: Seems like today's updates have fixed it. Looking at some of those updates, it seems they could be the same updates that were ready to go day 1. I wonder if mine didn't update for some reason. I did have it turn itself off due to overheating while updating.
If someone could confirm the initial updates by number for me, especially the date of the firmware update (just installed one dated 6/19), that would be great.
