As a developer the new keyboards have ruined macbooks for me - I find my macbook pro quite comfortable to type on for longer periods when I am away from my desk. I feel like the new keyboards are not practical for real use and it doesn't sound like the new models will greatly improve that which is a shame because I would love an upgrade.
I think those keyboards are great on the smaller more portable macbooks but I don't understand why the 'pro' models are favouring a couple of mm in size over a more practical keyboard designed for 'pro' use.
