So I just bought my new MacBook a few days ago and just bought the base model for $999. I absolutely love it! However, the multitasking isn't that great so I decided to buy 4gb of ram and see if that helps (didn't want to go 8gb, seems like too many issues/too much money). I like to keep music playing, some internet windows open, photoshop, and some torrent stuff going simultaneously. The other thing I didn't really like was the hard drive. It's only 250GB and 5400rpm. I was thinking of taking the hard drive that I just bought for my windows laptop, a Hitachi 500gb 7200rpm drive, and putting it into the MacBook. However, after reading all kinds of noise, vibration, and battery issues people have had in various forums I decided against it. I've got 4 1TB USB drives for my work and figured I can just use those for storage. Regardless, I love my MacBook and can see myself using it for years to come!
