I've been reading the recent rumors of a possible new MB unveiling (maybe in January?). I was just wondering, what do current MB owners think about this? I'm kind of new to the Mac side of things, but it seems to reason with the constant unveiling of new products by Apple, people get upgrade fever pretty often. I bought a 2Ghz C2D MB last January, and it's in extremely good condition (only 29 cycles on the battery), but I have this fear that in January this whole new line is going to be released...you know, complete with an increased memory limit, processing speed, ATi video (albeit very low end), and of course Leopard included. part of me screams 'Sell now! Buy again later!' while the other half thinks this computer is plenty powerful enough to get me through the next 3-5 years. what do you guys think? what is the normal behavior for Mac users in terms of upgrading/buying new Macs?
