will add my two cents too
LOVE the new retina macbook
its just perfect!!! its not too much bigger than the macbook pro 13 and its the same weight. of course its heavier than the macbook air, but gaffers there's a price to pay for more grunt... if you're just browsing the web, writing a few documents then I would get an air for sure. But if you're going to be somewhat productive, either in iMovie, coding, photoshop, gaming the screen space and the extra power is worth it to go for the retina macbook. The screen is the most amazing screen I've ever seen, put a smile of my face, it was like getting a new pair of glasses, the clarity is amazing.
i got a macbook aluminium early 2009 core 2 duo, the geek bench is 2900, the new base macbook retina is 10000+ so its a huge leap in performance. Can't wait to get it as soon as there's stock... stupid apple the only thing they keep wrecking is the launch... they can make beautiful products but their launches are absolutely terrible.
oh someone tried to argue with me yesterday about macs being overpriced... sure some of apple's options are overpriced but I think their base model macbook air especially their 13" base model is very competitive. and i think i understand why its overpriced... its built to order so they have to go out of their way to build it for u, whereas they must build plenty of base models.
also walked into JB hifi (australian electronics store), a mom and dad looking at computers, they commented that the air didn't have a disc drive and they had to have one.... the steam coming out of my ears
u can get an external drive which is a much better solution anyway!! I guess they didn't know that at the time but yeah still find it hard to believe people need to hold on to legacy technologies .... amazing... ppl still need to watch DVDs or play CDs or cassettes or think they will use it lots but in reality don't use it. security blanket!! anyways maybe they need it lots who knows... just think its usually mainstream people who are afraid of change.
