To me, 16GB of RAM instead of 8GB of RAM on a super thin, light, laptop is a pretty big upgrade. I used to be on a maxed out 17", happily switched to a maxed out 11", and am now beyond psyched to get my maxed 15".
Apple continues to disappoint. This kills any desire I had to buy one of these. If I can't keep upgrading it over the next few years as I need it, what is the point of buying this over an Air?
The point in buying it over the air remains: 15", retina, etc.
This is not something to be mad about. If you buy the maxed out 16GB, well, it's maxed out anyway.
If you buy the 8Gb, it's a compromise you make. You'll live with the 8GB, or sell the laptop to upgrade. It's worth the trade-off (small size, etc.)
The situation wouldn't be as bad on a 4-core/8 hardware thread MacBook, but you start throwing in virtual machines and various other processes and 8 gigs of RAM starts to look pretty anemic for hardware marketed to the "pro" user.
The new mbps hardly qualify as thin or light.
4.5lbs has never been considered "light" (Well, maybe back in the 90s)
And thin? It got like 15% thinner. You could fit 2 Airs or 3 vaios in its thickness.
I'm not trying to be a hater. I really really wanted to upgrade mac today but I was hoping for thin + light + retina and sadly that wasn't this time.
So I really have no idea what you are talking about about you being able to fit 2 or 3 Airs. You would think if you are about to spend $2000 that you would do some basic research.
