Windows XP

Many times I have lost much data due to XP being unstable, and very much infested with viruses and worms and trojans and malware (Even with a firewall, antivirus etc.) I highly reccomend that you do not buy XP as it is very unreliable. If you must use it (I do) because of program compatibility (ie. Linux cannot run the sims) then i suggest having a dual-boot alternative such as Linux (which is reliable and free, www.debian.org) or even an older version of windows such as Windows 98 or NT. If you own a buisness, you should probably do so. (for reliability purposes.)
