Windows is closed source, look at how it's developed....unstable, un-orderly, etc...
Linux has been open source and hasn't had a huge budget, but now it could EASILY compete with windows in the OS market if more software co mpanies would support it instead of worrying about those oversized TIs called macs ;D.
See what i'm trying to say?
Close source BAAAAAAAAAAD, unless you have a large team to continue development.
Open source gooooooooooooood, if you ever stop developing it, other's can.
