Ok scrap that. I succumbed barely a few hours later and asked my bro to get some parts for me. Bought an internal HDD and a portable one, together with 2 RAM sticks. There goes my X'mas budget. :( However I stupidly forgot to get a spare SATA cable, so I can't use the internal HDD yet, urgh. At least the RAM sticks work, though I've no way to check if the dual channel is working. Benchmark tests look ok though, so hurray.
I've just spent something like the past 3 days mostly offline and studying, omg. My desktop has been relegated to the corner, my laptop to the nearest shelf and the work table is a messy pile of notes, tutorials and reference books. This is the pits. I've been taking breaks, but you know breaks tend to last longer than they should, so the less breaks the better! Grr. This is not me man, not at all. So much to cover, so much to assimilate, so much to master.
Anyway. Anyone thinking of getting a MacBook Air, check this out. It's from: http://www.engadget.com/2009/11/26/macbook-air-meets-bus-bus-wins/. Apparently the freaky thing still works. Awesome.
