I wouldn't worry about creating bad sectors, any defragger that causes physical damage to your hard drive isn't a defragger, it's a virus. You should always run a disk check prior to defragging though, if a system file has corruption and then is defragged, it can make your system unbootable. I would agree that most people spend far more time defragging than they'll ever get back in saved time as a result.

Most of that is outside Microsoft's control. From my experience, most Microsoft software does uninstall fairly cleanly... you may find a registry key here or there or a folder it wasn't completely certain it was safe to remove, or even a shared DLL that doesn't really hurt anything, but usually nothing that actually compromises system performance. As for third party software vendors, they use a third-party install tool such as Wise or InstallShield and don't bother reading its documentation to learn anything about telling it about everything it has to remove in the event of an uninstall. Just check out the Non-Plug and Play section in Device Manager after an "uninstall" of Symantec Antivirus and you'll see what I mean. Microsoft can't force Symantec to learn how to properly script InstallShield.
From my experience, Linux install routines are so basic that uninstalling generally doesn't mean anything more than deleting a subfolder of /etc or /usr or something. If Microsoft started running install/uninstalls the way Linux does, they'd be going back 10+ years in time. No more entries on the Start menu, no more integration without a ton of your own work, etc. As crummy as uninstall routines are these days, spending the time to learn how to clean out your registry and Device Manager are a lot better than losing the convenience provided by properly scripted installations.
