Who has a Linux Based OS?
Dual-boot is a near-dream on my laptop. The installation is a piece of cake. The hardest thing was getting Vista to shrink my hard drive to make a new partition. My favorite thing is that I am able to boot both of them at the same time, kinda. If I boot up Vista then put Vista in hibernate I can start Ubunutu while Vista is still in hibernation. I haven't tested on hibernating Ubuntu though. Once I shut down Ubuntu and go back to Vista, Vista wakes up from hibernation as if nothing happened. It is faster that way compared to a clean boot. :D
Anyway, who cares if you really are serious or not. With Ubuntu, you can still run Windows progams. I just ran HL2 under Ubuntu (7.10 Gutsy). You just gotta try Ubuntu and see how incredible it is. There is more to Ubuntu than you think. Think of it this way, Ubuntu has everything Vista has with less CPU/RAM requirements (32MB minimum, 512 MB recommended; 300Mhz minimum, 500Mhz recommended ) with tons more stuff and is completely customizable.
The support for Ubuntu is the best I have seen. Go to ubuntu.com and take a look at their forum and see how many people are there to help out. Now, go to microsoft.com and take a look at their support page. Microsoft's support is absolutely useless. You can't even report a bug to them without having the program crash on you. Speaking of crash, Ubuntu never ever crashed on me under a stress test with 36 tabs in Firefox open (and saved) games running on another desktop (Ubuntu allows you to have unlimited desktops to eliminate clutter; you simply rotate the screen and voila) while updating Ubuntu on a third screen. I even made 1000 (yes a thousand) rows and 16 columns of desktop screens and yet it still doesn't lag even with full desktop effects enabled.
I can't explain how amazing Ubuntu is. I also realized how freaking BUGGY Vista really is.
Note: Sorry if this is too long. It just has unlimited things to do on there. (I'm even on Ubuntu right now typing this.) It is just flatout insane with Ubuntu. :D
