I purchased my current Macbook 1,1 in June of 2006 -- immediately before my senior year of college. It served me well through the end of college, graduate school, and now as a teacher. I, however, think it's about time to upgrade. My current specs are: 2.0ghz Core Duo 80 GB hard drive 2 GB Ram (unfortunately, maxed out on this early model). Snow Leopard Problems: Discs get stuck in the optical drive (Had this serviced under Applecare but didn't fix the problem) Screen flickers (Same as above) Occasionally runs REALLY slowly -- when I run Onyx it seems to fix this. Honesty, though, for the most part this is a great machine. It's still relatively quick and I am planning on keeping it even if/when I purchased a new Mac. I will use my new Mac for the following purposes: Grade programs, MS Office Suite, Hulu, Youtube (I love watching Pro SC matches in Korea... It's a guilty pleasure), and occasionally a game or two (but nothing new... I like Roller Coaster Tycoon and old CC Red Alert type games... Though Fable III looks pretty awesome). Portability is somewhat important as I carry my current Macbook to and from school everyday. This model is 5.3 lbs, so I feel like I could handle anything around that weight with no problem, but wouldn't complain if I had something lighter. Most importantly, though, is I want something that will last me another 4-5 years just as this one has. So, with all that said... It's either the new MB Air 13" maxed out... Or I wait for the MBP (13 or 15") upgrades in early 2011. As long my computer can hold up, I have no problem at all waiting until Spring. Any suggestions, advice would be great. I think the MB Air could probably handle anything I am going to be using it for with ease, I just worry that the technology won't hold up for four or five years. Thanks for your time, all.
