This is such an obviously biased web site I hope this backfires. I really do think that many people will see that M$ are actually scared of something, and wonder what they are scared off.
For me, i took the Pepsi challenge, I'd ordered tickets for a gig. and being the UK there was a postal strike, so the tickets didn't arrive. I got an email from the promoter saying that the email was may ticket, all i had to do was print it take it with me..
I'd just rebuilt 2 PCs, one with Ubuntu and one with XP, but had never connected up ther printer to either, and the gig was in 40 minutes, so i had to get a print out.
Connected printer to XP box.... waited, got a message saying something had happened to a USB port and it was going to look for drivers and stuff..... a few minuts later it still had no idea what had happened to the USB port and was asking me for help.. I wondered if Ubuntu would fare better as I was getting nowhere with XP.
Connected printer to Ubuntu box, got a message straight away saying "You have connected a HP 5250 Printer, please wait a moment". Then, literally a moment later i had the "device ready" message. 650 seconds later i was making my way out of the door with ticket in hand.
Now, I bought the XP box from eBay with a pre-installed XP for £45. and Ubuntu is free, although I did wait 3 weeks for the CD. (i could have downloaded it but decided to get the original disk for fun).... If i had paid full price for the PC and XP I would have immediately declared the purchase to be not fit for purpose. Ubuntu however, has been great with everything I've connected to it. It's occasionaly awkward, but nothing mind blowing. And it reads NTFS drives without a problem. Windows does not read anything else apart from FAT or NTFS without a big hoo har, and the last time I did try setting up XP to read ext3 it ruined the permissions on that drive and rendered it useless so I had to re-install it.
XP = £££ and is not great.
Ubuntu = Free and is wonderful
Conclusion, if Ubuntu was £££ i'd only be unhappy because the graphical layout looks like an amateur "My First PC" style... where as XP looks ace and is very slick looking, but is essentially shit for the money....
