Well, congratulations for the Linux.com launch. Now onto other things.
I bought a new PC, and it just came in. Installed Windows 7 and Jaunty, both 64 bit editions. I must say I am equally impressed by MS and Canonical. Windows 7 picked up my wireless out of the box. This has never happened before for me. I'm not doing a review, so I'll sum it in little. 7 is what Vista should've been. And it's good. It's streamlined, less resource hungry, and just a nicer experience. The interfaces are intuitive, but a little awkward to use. Other than that I must say 7 is nice.
Ubuntu too, installed fast, easy to upgrade, supported my wireless out of the box. Nvidia was easy to configure with restricted drivers. It's easy to navigate, install apps, fast, and not at all resource hungry. Good job.
Overall both systems are nice, and I suggest you try Windows 7 if you're able.
