Windows often requires restart, which is annoying, but let's face it, not that important. Linux seldom requires restart update (after kernel update mostly), but than again, do we really need 100% uptime for a desktop? A major difference, and really a big fault on Windows, is constant nagging to reboot, with window that pops up every 10 minutes or so. Ubuntu has really good visual cue (power off applet turns to red, see upper right corner) but allows the user to make that decision to restart when convenient.
