Is the aluminum MacBook worth the extra $300.00? Absolutely, but not if you suffer from astignatism
I have astigmatism as well...but I do not suffer from the problems you were talking about. I guess mine isn't as "severe" as yours or whatever, but for me...I actually have to take my glasses off to relieve my eyes. If I keep my glasses on, my eyes tend to get tired a lot faster than without them on.
But to get back on topic. I just have a quick story to tell. When my sister got her White Macbook in September, I thought I was totally sold on getting the black one as soon as I saved enough money, but I was always debating on that since I loved the aluminum body of the Pro. Then there were rumors of new macbooks WITH the aluminum casing, so I waited. Once the new ones were announced, I pretty much fell in love with the new design, so I jumped on it from waiting and ordered one. When it arrived, I was in shock how well built the computer was. A TON more sturdy, and it just feels that Apple really did their job on the unibody design.
The screen, at least to me, is a significant upgrade from the last gen, comparing mine and my sister's, my screen is around twice as bright as hers. Also, the screen, again, at least to me, has a bit better viewing angles side to side compared to the last gen. I didn't really look at the up to down angles, but I honestly doubt someone is going to be straight above your head looking at the screen with you. However, it does seem like the up angles are better than the down angles, if that makes sense. When her's was at full brightness, mine was half getting the same output.
Also, the sound was greatly improved, as we were testing movies (Ratatouille
🙂) and the sound coming from mine was a lot clearer, and louder without distorting at the louder volumes as much as hers did.
The new trackpad is pretty much BLISS! I love it compared to the last gen macbooks. The glass just feels so much nicer (kinda obvious). And of course the multitouch that you can't get on the white macbook, I'm not sure if it goes for everyone, but it made my experience navigating around OS X a lot nicer and more fluid.
So to me...the price difference WAS worth it...in Canada, the price difference between hers and mine was 400 dollars (White 2.4 $1349, Aluminum 2.4 $1749) and I still think the "upgrades" or whatever you want to call them are worth it. Of course, much of what I said could be taken as subjective...but at least you now have someone that has used both quite a bit, and real comparisons between the two about the new "features". I didn't talk about Firewire, since neither me nor my sister use it, so that was never a problem for either of us, mainly me since my computer doesn't have it.
