Hi Guys, Brand new to the forum -- pretty excited to be here, because I'm about to purchase a Macbook (MC207LL/A), hopefully by the end of this week. Just a few high-level questions first: 1. Should I go with this model, or wait for the next one to come out? 2. I saw the Micro Center price is for $799 -- any better deals out there? 3. Is there a difference between purchasing from Micro Center, or at the Apple Store (assuming they'll price-match)? 4. What's the difference between the old style, and the new unibody style? Is palm rest cracking still an issue, etc.? Thanks!!
