I like Linux myself, but the two are related on a core level. Mac and Linux.
I see a market for someone who can take Linux to the next level. I see The Linspire people as doing a good deal towards offering alternatives, but there could be more done. I would like to make an offer. Everyone who owns a computer could send me $10. I would then take that money and create a brand new operating system with internet access for free, email client, and word processor, spreadsheet, and database capabitlities. All for the cost of a harddrive (about $200). You would recieve lifetime support, and lifetime upgrades to your software. You could also create low cost task specific systems. I.E. gaming systems, graphics systems, audio file creation systems, etc. etc. These systems could come with preinstalled software that automatically starts at boot time.
