Thanks to my laptop suddenly deciding it won't last for another year or two like I hoped it would, I've been thrust into purchasing a new laptop (which would be great and all, if the circumstances would've been a year down the road instead of now). So I've been looking into an iBook or a Powerbook with costs under the $1,500 mark (with the educational discount). There are two configurations I'm torn over: 1) 12" Powerbook, 768 MB DDR333, 60 GB hard drive, combo, and a 1.5 GHz G4 - $1,467 or 2) 14" iBook, 768 MB DDR266, 80 GB hard drive, combo, 1.33 GHz G4 - $1,379.0 I primarily will use it for internet/word processing and some photo stuff here and there (my iMac will do the grunt work). But I'm worried that the performance of the laptop will slow down as time goes on as it has on my iMac. Therefore, which would be better and provide better performance in the long run? I know the basics of memory and processor, yet I can't differentiate the essential differences that would come in choosing a 1.5 over a 1.33 G4. Hard drive space isn't really that important since I've been considering an external so I can edit video moreso than I can currently with the iMac; as is the difference in price. Essentially, I'm looking for a reliable, consistently high-performance laptop as time goes on (I won't go over 768 MB if I don't have to, I don't want/can't really afford to spend the extra $300). Thoughts?
