Hello All, It has been a while since I have been in the market for a new computer. I've managed to hang on to my 12-in. PowerBook G4 since 2003! So, it's time for an upgrade, now that the new 2010 line of MBPs have been released. So far, I'm leaning towards getting the 15" i7 2.66 Ghz, with an 8 GB RAM. My dilemma is whether to stick with the 500 GB HDD that it comes with or "upgrade" to Apple's stock Solid State Drive. I'm not a techie, but I've been reading a little bit about the pros and cons of SSDs. It's a pricey option (especially for the top-tier 512GB), so I thought it merited further consideration. I'm particularly interested in your thoughts about the longevity of these drives (decay, degradation?), SLC vs MLC drives, and whether or not Apple's stock SSD drives are a good value overall. (Anybody know which brand(s) Apple uses?) The salesperson with whom I spoke at the Apple store didn't seem to know much about the machine's internals. I've had much better success searching answers in these discussion boards, so I thought I'd give it a shot. Your experienced and thoughtful insight is always appreciated. Thanks in advance! Cheers!
