I'm starting to get the upgrade itch again, with the added "pressure" of my cousin looking for a new laptop that will last 2 years or so. She's looking at the $999 MB, but my Santa Rosa 15" MBP with almost a year's worth of Applecare left seems to have roughly the same specs, and I'd sell it to her for ~$500. I'm still trying to figure out of it's a good idea or not, but I'm leaning ever-so-slightly for the new laptop (15" mid/high, possibly 17"). As they say, always put together a pros and cons list, so here's mine: Pros: + I get a new laptop and help a relative on a tight budget + Faster processor (and easier to run 64-bit OSes) + Better graphics + More HD space + Longer battery life + Lighter (unless I have to go 17" for anti-glare) Cons: - Only 17" has anti-glare (heavier and I'd need a new laptop bag) - Non-user battery replacement makes me a little twitchy - I keep on hearing about Arrandale being a big deal - Don't want to saddle my cousin with potential 8600M problems (although I haven't had any) - Blu-ray drives possible next year FWIW, I'm not doing HD video editing or anything like that, most of the power is used for mobile gaming (Steam) under Boot Camp w/Windows 7 RC or video streaming/playback including HD. And I'm not sure what, if any, benefits Arrandale would bring to a more casual user like me. Blu-ray would be cool, but I already have a Blu-ray player for my home theater, although a burner (however unlikely) would be sweet. However, I haven't had much experience with glossy screens, and I've yet to check one out at an Apple Store, but if it ends up being a big deal I'm limited to only the 17". And although my employer provides interest-free "layaway" for Apple purchases, being limited to the top-tier laptop would give me pause. With all of that in mind, what would you say?
