I'm a college teacher whose 5 yr. old 14" G3 iBook just died. So, it's time to replace the well-loved workhorse with another that I hope lasts me just as long. I really need to get the most value for my dollars since this is an unanticipated expense (I know--5 yrs old & I thought it wouldn't need replaced soon?) on top of an expensive year financially for me. I have to buy within a few weeks since I must have it ready to go for school the third week in Aug. I will be using it primarily for word processing, powerpoint lecture presentations, internet, & statistical analyses, so I can't decide whether or not to go with the base 2.0Ghz model or the middle priced 2.16Ghz model. On the face of it, it seems that I should spend the extra $200 to get the superdrive & larger hard drive, but would it be better to use that $200 to upgrade the base model's RAM to 2 GB? I won't be using it for games, but admit that I would like to be able to burn onto DVD some of the movies I've bought from iTunes, but could always buy an external dvd burner later if I really felt the need.
