well, i am using win98SE for a few years now (3 reformats), i sued win3.11 for a year or 2, and i learned DOS when i was 6.
dos, never crashed, win3.11, i took it down once or twice, and 98SE is going down 3 times a day. linux, never, ever, crashed.
also, the security features in linux seem a lot better, and all the sttings are easier to find. and, a major feature, it is free. i won;t pay 1100 Euro for XP Pro, and then another 400Euro for office 2003 or wahtever it'scalled. these are the prices where iot's going now here, and a Euro is about a dollar. for linux, i download 3 discs, and get:
an OS comparable to XP = 1100
an office packet, better them MS Office = 300
a image editor like PSP = 700
a whole bunch of programming tools = 100 (probably more, but let's go easy)
and a lot of usefull apps, which you would have to download sepreately under windows. i get a total of 2200 Euro's spared, by downloading 3 discs. and for compatility, you can always run your old windows next to linux, or wait untill it's ported. which happens a lot to some older games.
