I just started a one-man design company and need to get a new computer. I've been using an eMac from July 2003 but that thing is slow and slower. I'm thinking about getting an iMac (probably 17" 2GHz) and combing screens with my eMac screen (is that possible?). I don't want to spend a ton of money on a PowerMac because I'll want to upgrade in another year or two. Question is, will an iMac work well for at least 2 years or should I get PB that hauls ass? What if I bump the RAM up to 1GB? That should do the trick, right?
