Hello, everyone! I believe I'm going to buy a rev. C 12" powerbook fairly soon and found out it has 256 built-in with one other memory slot. Looking at crucial.com they have either 512MB for a nice, low $117 or they have 1GB for $480! You can see which way I'm leaning. So my question to current 12" pb owners is 768MB enough memory (which would be the 256 built in with a 512 chip), or do I need to bite the bullet and buy more? I know OS X is quite memory intensive. I currently have a 15" TiBook (1GHz with 1GB of memory) and it works great; smooth and fast. Should I expect the same results on a 12" with a faster 1.33 processor but with less memory? Any and all advice welcome! Thanks, everyone!
