I have had the Windows 7 Beta and Release Candidate since they were available, but after the RC expired, I bought the full version of it, and I have to say, it’s pretty awesome. It has the performance and reliability of XP combined with the graphical improvements Vista made, and then some. I didn’t have any driver problems, because almost anything that ran with Vista will run on 7. The new taskbar (called the superbar) is great, because when you have a powerful computer running multiple applications, you can see them all by mousing over them. You can also pin file’s and program’s icons to the taskbar to quickly and easily open them. A new feature supported by many popular apps, such as Valve’s Steam, Mozilla Firefox, and any built-in Windows program, is something called Jumplists. They are menus that pop-up when you click a program’s icon and drag it upward. They can show different things depending on the program, but they will usually show options, recent files, and common actions for the game. I installed Windows 7 on my laptop, which is an ASUS Eee PC 904HA, and it runs very well for the speed of the laptop, comparable to XP. My desktop absolutely flies, but it’s running a quad-core processor and 4 gigs of RAM. Windows 7 is by far the easiest to network on as well. Most wireless cards are detected when you install it, and Homegroups are supported. Homegroups are an easy way to send media and files through your network, and are much easier to use than workgroups. The problem is, they only work with windows 7 computers. The good news is they are still backwards-compatible with  older computers by using the traditional workgroup setup, which seems to work just as well, if not better, as it did before. There are only 3 versions, Home Premium, Professional, and Ultimate. Home premium is is the best for home, media, and games, and is around $180 for a full version and $120 for an upgrade. Professional is equivalent to the Business edition of Vista, and goes for around $270 full, $180 upgrade. Ultimate combines all of it, and has everything, including an XP emulation program and Bitlocker encryption. It is $320 full, $220 upgrade.
