Haha, 32 gb is enough for me at the moment, but I am sure that the engineers at google are doing their best to make sure that chrome consumes record amounts of ram per tab, so soon 32 will no longer be enough.
I'd be very happy with the 32GB at this point, but sadly my company just got me the previous new model with 16GB and I doubt I can convince anyone to reduce my refresh cycle to mere months.
Honestly, this looks like a good revision. I've been wanting a quad core 13 inch for a while.
Hopefully the keyboard revision helps with all of the issues people have had.
