Okay, my grandfather's dell laptop is horribly slow. I want to buy him a new computer thats runs faster for his emails/videos. I was looking at the old imacs/emacs on ebay (the 2000-2005) versions. These comps fit in his budget of approx 100$. I was planning to buy an iMac/emac with the following specs 500mhz (or faster) Processor (or 600/700mhz) 256mb (or more) Ram (512mb) 20gb Hard drive (adding external memory) with the newer os x operating system. My question will these computers fit his needs? He writes emails, he writes a ton of word documents, and he views videos off youtube and off a media player. My question is that will these spec'd computers be able to run his needs efficiently? Are there programs that are similar to the windows (which he is used to)? Can you run microsoft office on these computers? If not what would be the recommended specs I should look for? Good Website to purchase other than ebay? I never had any experience with older macs, only with my cousins newer macbook pro.
