I am a switcher from Windows. I no longer have my PC (gave it away). I have some Windows software I would like to use. Specifically, Garmin GPS and DeLORME Topo USA. Neither of these have Mac versions. My Mac hardware is: Mac mini, 1.25Ghz, 512MB, 40GB HD, 20" Apple Cinema Display, BT keyboard and Mighty Mouse. My questions are: 1. Is my hardware adequate to run Virtual PC? 2. Does it work? 3. Would it work better if I had an ext. HD? 4. Once I have it running, does it work like a Windows machine? That is would I install the Windows applications as I normally would on a PC? 5.Recommendations? Thanks for any help.
