not all graphical DOS programs are games, partition magic 6 has a DOS only version with a GUI, and what about the arachne browser? it does not require windows to be running. i think the linux version does not require X to be running either, and as another non-X GUI linux tool, what about pkgtool and pkgtool2 which are package management tools (surprisingly enough) bundled with slackware and peanut linuces respectively.
this thread is quite irritating to me because nobody's really got to the meat of the matter as far as i can see.
NTFS is a closed standard filesystem. it is not reliably supported on any system other than later versions of winNT (to my knowledge) purely because of the designers' decision to make it that way. Latterday linux filesystems such as Ext3, ReiserFS and XFS (if i hear rightly) do journaling, and keep themselves clean, tidy, fast and free of errors and are also all open standards, meaning microsoft could implement windows support for them tomorrow if a) they wanted to truly advance computing and b) they really wanted to prove their closed source development model is in any way workable. but they don't so draw your own conclusions.
