Yeah, good point about the keyboard. Forgot about that. IMO Apple spends too much time worrying about carrying a laptop vs using a laptop.
For the life of me, I don't understand how a laptop that weighs .5 lbs lighter and 3 mm thinner is any more or less "portable." That word drives me nuts. If you can't carry around a 4 lb laptop cause it's noticably heavier than a 3 lb one, you need to worry more about lifting weights and less about computers.
Infuriates me. What were we talking about? Oh yeah, the keyboard. Definitely hear a lot of complaints, but I've noticed that a lot of people that actually own one quickly warm up to it.
Personally, I'd prefer a bit more travel, and I'd sacrifice a mm or two, especially if it netted me even better battery life, but I've definitely warmed up to it. There's no question I can type faster, and I like the size of the actual keys. I don't get people that complain about the noise, but if I'm gonna talk about coil whine I have to be consistent (though keyboard noise honestly doesn't bother me like coil whine for whatever reason).
But yeah, it definitely grew on me, and from most people I've interacted with, they feel the same. Fair complaint though.
A lot of the complaints from people who actually own the new MBP are about the keys starting to make annoying clicking sounds after the keyboard gets hot. Does seem to be an issue that Apple missed somehow. Numerous threads about it here.
I personally prefer the machine to be as light as possible, more when it's actually on my lap than when I'm carrying it. A lot of people opt for the 13" because of the size and weight.
