I’m currently testing out the (free) Release Candidate (a kind of late Beta) for Windows 7. Long story short, Windows 7 is awesome and I’ll definitely be picking up a copy when the full version is released. Anyone who installs the Windows 7 RC has until March of 2010 before they even have to think about spending a dime. The new taskbar, improved memory management, Libraries, Themes, HomeGroups, Device Stage, chilled UAC, and increased zippyness make this a solid (though not essential) upgrade for Vista users. This is Microsoft’s best shot at getting entrenched XP users into the 21st century.
