EXACTLY.
linux is tiny, as we know, it's about 26 Mb by itself. AND it can run with a lot less RAM than windows can et cetera etcetera.
If you want a lot of programs and stuff, then you have to have the disk space to install them. I can seriously say that on my hard drive, which is 12 Gb, linux looks set to NEVER need more than 2Gb. With the windows side i have had to constantly increase the size of the windows partition, to accomodate the programs i want to install. I have a dozen or maybe a bit more applications installed in windows and it's up to 4 Gb. This does NOT include the my documents folder or any files i may be storing, they are on a separate partition again. The 2Gb linux side on the other hand has many full applications i still haven't discovered yet, and much free space for any more i may find and download.
FINALLY, to that guy a few posts before who's happy with win98 and who thinks dual booting would be difficult, you say in the very next sentence that you never bothered to try it so why are you criticising? you imply that we should not be telling you to change to linux, but at least we have tried windows ourselves and come to a rational conclusion. You however are not only willing to cry down something you have never tried, but you make up little storied about how it will be too difficult for you anyway!
Horsewallop. I don't care if you use windows 98 exclusively, but at least be honest about your reasons!
