I would really appreciate peoples opinions on which of these is the best for running on win xp. Im looking for stability, and compatibility with xp. I dont want something that is likely to trash my xp install. I know this is a bit of a wide open question, but if anone has experince of both or either of these id really like to hear what you think of them, the pros and cons of each etc. Personally Im leaning toward Virtual PC, being its from Microsft Im inclined to think it will hav ebetter compatibility ans stability - is that a wrong assunption? Hope someone can shed some light on this as Ive never used a virtual machine before, in the past Ive always used drive racks but thats no longer an option. ps: Hi and nice forums!
