I'm finally ready to make the switch to the Mac. However, before I do so I still have a few questions.... First, I plan on using the computer for school work (word processing, spreadsheets, internet/email, etc.), as well as for java programming and familiarizing myself with a Unix environment. However, price is an issue. Basically, I'm looking for advice on what type of specs I'm going to need on the computer in order to run OS X at a decent speed? I've been doing some searches on eBay and have found quite a few of the older emacs (333 - 600 mhz) for about the right price I'm looking at to get started. Would a 333 mhz machine run OS X fairly well? If so how much RAM would you suggest having in it? Also, please keep in mind that while I'm trying to get the best bang for the buck, I don't want to buy something that isn't going to be any good to me in the near future. If I need something faster, please let me know what you think. Thanks for your help!
