Hello everyone, I don't know if you ever feel discouraged or somehow not happy with your current computer. Wanting more, wanting less, or just wanting the satisfaction that you've got reliable software. I'm currently working with a Rev. A (Core Duo) MacBook 2.0Ghz. And so far, I'm running into more and more problems. I have a huge issue with flickering display, the USB makes a strange beeping when more than one device is plugged in. I already had one HD fail and I'm running on the one that came with it....which happens to be the ill-fated Seagate 7.01... I'm afraid that my machine is a ticking time-bomb. I'm out of warranty (bought in Oct. 06) and no AppleCare. . Part of me wants to downgrade by selling this one eBay and possibly investing in a PowerBook 12"? Am I overreacting? I'm not sure what's the best course of action. I don't use my MacBook for anything other than school, word processing, and internet.
