I’ve recently purchased a second hand unibody aluminium MacBook. Now the specificaion in terms of speed is very similar to my previous Black MacBook. Main differences is .2ghz speed increase and almost double memory speed increase. Other than that all the other differences are cosmetic and usability and its incredible how much better (even following a particularly good Black MacBook) this new one is. The LED screen colours are just incredible. I get a much brighter screen without loosing additional battery life. The back-light keyboard is surprisingly helpful in dark situations (after living without it for so long you forget that it’s even a feature that could be useful.) And let’s not forget the aluminium enclosure and multi-trackpad. It just makes using expose a million times easier, the body is stronger, lighter and so much more robust.

Even minimal things such as the displayPort. It just holds in an external display connection much better than the previously poor miniDVI connection which would come loose at frequent intervals. Oh and you don’t get that annoying sound from the superdrive when waking the Mac up from sleep. Silent wake. Lovely.

Best thing is that they go for anywhere between £600 and £700 on eBay which is over £250 cheaper than the current 13” MacBook Pro on the Apple website. So, if your thinking of upgrading your current polycarbonate MacBook for a faster machine, don’t go for another one, go for a second hand Alu MacBook from eBay or a MacBook Pro from Apple.
