You know I would hate to see you buy a PC. Even though I am beyond frustrated by these problems with my MacBook, when it is up and running I absolutely love it. Maybe I should just figure out a way that I would never have to shut it down and I would just be ok. Not practical since I travel with it.....
I guess let me say this. PC's are a problem all day long, every day. I used PC's for the majority of my career (let's just say a very long time) and Mac's for only the last 2. Buying a Mac was the best technology purchase I ever made but I started with a PowerPC. If this MacBook was my first now maybe I might have a different opinion.
I have my problem with my MacBook just on start up, for now anyway. (I'm keeping my fingers crossed that it doesn't get worse). With PC's you have to worry about the spyware issue and the continual virus issues. You spend a good deal of time, energy and money dealing with that issue alone. The software doesn't integrate nearly as well on a PC and they aren't as intuitive or easy to use, in my opinion. There isn't anything that I can think of that I don't like better on a Mac than a PC.
I would suggest this. I don't know if this particular problem is limited to the 13 inch MacBook or not. If you have the ability to deal with the size and or the price difference, I'd look at the boards on the MacBook Pro and see if that model is experiencing the same problem. If it isn't, maybe go for the MacBook Pro instead of the MacBook. If it is, I'd wait as long as you can before you absolutely have to buy your computer before you go to school. I find it hard to believe that, given the number of reported issues about this, some solution isn't coming soon. Maybe a month would do it.
If at a month you check the boards and it still looks like the issue is happening, why don't you look on eBay and see if you can find yourself a newer model, used PowerPC. The driver for me buying a MacBook was that I needed a faster processor and a larger hard drive in a laptop model, that could also run a couple of Windows XP programs that my clients have (like Microsoft Visio) faster. That just wasn't feasible running in Virtual PC. However, for standard word processing and other computing tasks, my PowerPC was great. If you also didn't need any Windows XP programs or didn't need high performance from them, Virtual PC worked really well for occasional light use.
That would be my suggestion.
