I'm on the upgrade/switcher path for my wife from a Windows PC. I'm considering an iMac 24" but that may be too much mac for her so I'm thinking a Mac mini. One of the dilemmas is that she uses dual monitors to expand her desktop...has a browser running on her 17" laptop and an excel spreadsheet on her 19" external display. I think I can get her accustomed to a single 24" wide screen display plus Spaces. However, I don't know if the mini has enough horsepower to run a 24" display at 1900 x 1200. Any first hand experiences? Thanks.
