So here is my deal. Back in April I got myself a MBP core duo with a couple of upgrades, and it has been great. However, I have found myself not using all of the potential power of the machine, and when I do, it is to play a game on the windows partitan. Add to that the 3 repairs and a replacement, and now a superdrive that dosen't work all the time, and I'm just getting tired of it all. What I have been thinking about lately is selling my MBP and buying a low-end refurb macbook, as I love OS X and I need mobility, but I find that I only use it for casual stuff like internet and chat, and then buying a sub- $1000 gaming PC to play games on. I am really conflicted, and rather angry with myself for wanting to change things up again (I feel like I am never happy with what I have, and that I always want the latest and greatest, but in this case I am downgrading, so I don't know what to think). Anyway, at this point I have no idea what I want to do, but am looking for advice from my favorite online community. What I guess I'd like to hear is people's experiances with low-end CD macbooks (how does OS X run with 512mb of RAM as opposed to the 1gb I am used to?), and people's experiances with two-system set-ups, especially mac/PC ones. Also, I am throwing this whole idea out to you guys before I have done a lot of research myself, but any horror/sucess stories with selling "big ticket" items through craigslist? (I'm avoiding ebay like the plauge...just can't deal with scammers and the like at the moment), and does anyone have advice on places to buy cheap gaming PCs/what exactly to put in my cheao gaming PC, or, since this is a mac forum, does anyone have advice on where to go to get PC advice? (And I don't mean PCrumors ) And finally, I am looking for advice on whether or not I should even be considering this...even the most rabid mac-fanboy (remember, here that isn't an insult! ) reasons for not doing this will be taken into consideration in my mildly addled brain. Thanks!
