This is more traffic than we have ever seen in these MBA forums. It is definitely the $999 starting price tag that made this happen. Apple was so smart to start the 11" with only 2GB of RAM and 64GB NAND Flash to get to the $999 price point. It doesn't even matter if most spend a lot more than $999. It's perceived barrier to entry that has been substantially eliminated. Everyone can afford $999 if they want a Mac, as the MB is only $999 and it's Apple's entry level Mac.
The updates weren't as big as most of us long-term users wanted, but apparently Apple knows what it's doing. It has hit the sweet spot for so many by allowing this much bigger range of MBAs. Whether you want to spend $999 or $1799, you can buy a Mac that is really mobile and really fast. All of the rest of the details come down to needs, but the vast majority of users are going to feel like this MBAs are faster than their MBs and MBPs, even with 1.4 GHz to 2.13 GHz CPUs.
Nice thread.
