Hey everyone, I own an early 2008 (I think?) MBP. Coconutbattery says it is 34 months old. It is the aluminum body 15" 2.4 ghz Intel Core 2 Duo w/ 2gig of ram and Nvidia 8600M GT. It has run flawlessly. Thankfully, no problems with the video card, either...although, the only game I have ever played on it is Starcraft 2. Anyways, aside from some loud fan noise when playing Starcraft or watching a long movie, it has been a great computer. The battery is at 61% capacity.Unfortunately, I've recently gone back to graduate school...so I don't have a ton of liquid assets. My question: Is it worth it to consider upgrading to 4gig of ram, a larger HDD, and maybe a new battery...or to hold onto it until it dies? I'm going to assume conventional wisdom is not to invest any money into it, and to just hold onto it until it dies...I suppose I'm looking to see what the life expectancy for this thing is. Honestly, I didn't expect it to make it this long. Part of me fears that I will wake up one morning and it will be dead. Especially since not as much of my research is backed up as it should be. Similar experiences?
