hi, i'm new to the forum but recently been lurking, well I have a macbook and the keys are fairly decent but I have tried laptops with better keyboards.
My old Sony Vaio QR20 it felt weird for a week but then I fell in love with the keyboard, it had concave keys and felt more springier than the macbook keyboard. Its very old and I don't think Sony used this keyboard anywhere else, the keys did feel a bit plasticky but once you started loving the keyboard it became a non issue, each key is still working fine and the laptop is just used as a spare net pc. I've haven't used a mac keyboard (excluding macbook) since 10 years ago, so my experience is probably biased.
Anyway the macbook keyboard is fine but it is very flat and just doesn't invite your fingers to press them, and the short travel is fine but doesn't do it any favours from reaching the hard landing, i prefer a bit more travel in them other wise apple made a decent keyboard to go with their laptop.
Still getting used to apple keyboard british layout which is a combination of pc british and US layout which takes some getting used to especially symbol keys are thrown this way and that the fact the # key is hidden behind ctrl shift 3 is messed up. One thing is for sure the keyboard looks great as it is very modern looking where each key is clearly defined and that is what Apple is looking for in order push more orders to trendy cool looking gear rather than functionality.
