Im handing my MB to my wife when she goes back to work in september, and will be replacing it with either 24" iMac (2.8ghz, with 4gb) or 15" MBP (2.4ghz, 4gb, 7200rpm drive) + 24" LCD Im having a heck of a time deciding which route to take. imac pros: faster and cheaper imac cons: married to desk mbp pros: mobile when i want it to be mbp cons: slightly? slower, more expensive notes: storage is not an issue, file server all data. I do very minimal gaming, so im sure both will be adequate. Video editing newbie, web surfer etc.. Essentially the concern i have is, with both having equal amount of ram, and same speed HDDs, will the performance be that noticable between the two processor and video cards? Coming from a MB with 2gb, and 5400rpm drive, both will be a big step up. Assuming they are close enough in speed, is 600$ worth the price of mobility.
