Hi Guys, I hope this is the right place to post, first time here. I have an ancient Macbook from 2006 (I looked up the serial, I had no idea it was quite that old!) It has the intel core duo processor but is in reasonable health and I installed plenty of RAM a few years back. Its obviously not updateable anymore so I am stuck with snow leapard, I can't update google chrome or firefox either which is annoying, but not the end of the world for me. The body of is also falling apart, I've lost a lot of the outer casing and I have 3 keys missing. Trackpad is also dodgy. I'm looking to buy another Macbook on ebay that I put my hard drive into and also my extra RAM. I'm not sure whether to go for the same model or whether to get a (slightly!) newer model like 2010 or 2012 OR whether to upgrade further to something with a newer chip that I can actually update? My budget is fairly limited, £300 max. I just wondered if anyone has any knowledge of the compatibility of the models with eachothers parts? OR general advice, what would you do? Oh! Ideally I'd like to be able to use the same battery and power cable as both are fairly new. Thank you!
