The only thing it's good for is surfing the internet.. That's like the only reason i think the company made it. People have quoted it "Broadband PC". Now to the OS Favorites... IT ALL DEPENDS ON what ur gonna use it for... If you're gonna game, i've found that windows98SE is really good because it's not a memory eater like XP editions... but since i got new comp and stuff i guess XP pro would be my pick for everything... Just make sure u got lots of ram.. Anything else? i like macs a little bit..(don't hurt me).... they have good OS design and it is pretty stable compared the Windows OS's.... but i guess i'm still a Windows Fan. Probably always will be.
