Daily Techno-Babble offers a breathless "three reasons why Windows Vista is sinking like a rock," and while the story has a point, I don't really think that "limits on how Vista can be used under virtualization" is really the thing about Vista that is scaring away that many would-be users, nor are Microsoft's DRM provisions on high-definition video much of a big deal yet, as few users care about high-def on their PC right now. Don't get me wrong: I think all of these are factors that make Vista a poor OS, but they aren't the primary reason that it's "sinking like a rock."

Given that Vista sales seem lackluster at best, what's the hang-up? I think it's something far more simple than the reasons that DTB offers up.

So what's turning people off of Vista? Here's my take, in order of importance:

1) Price. There's no way around this one. Upgrading to Vista doesn't just mean spending up to $400 on software, but also cash on RAM and video card upgrades, or buying a new PC altogether. If Vista was a $100 upgrade that anyone could use, it'd be a top seller, I'm sure.

2) Nothing new to see here. Love the visual style, but does photo tagging and 3-D window flipping really merit an upgrade?

3) It's annoying. I don't know any Vista user who hasn't turned off User Account Control, which nags you with an "Are you sure????" prompt every time you try to do anything beyond run the calculator. Yet UAC is the linchpin of Vista's vaunted new security system. Without it, it's really no different than XP.

4) Tons of stuff is incompatible with Vista. An acquaintance of mine got a new PC with Vista preinstalled. Neither her scanner nor her printer had Vista drivers ready. Both peripherals cost several hundred bucks, and now they're essentially paperweights (though the printer, at some unforseeable time in the future, may work again). Lots of software won't run on Vista, either, but it's the hardware incompatibilities that are daunting. (Update: Looks like the scanner driver's finally ready.)

5) It's confusing. Everything that XP could do, Vista can do... only it's buried under a different menu and it has a new name. While average users probably never use many of these settings, power users have found themselves starting from scratch to relearn Windows.

6) It's busted. Try connecting to a printer on your network that's hooked up to an XP machine. Or try downloading a file with a third-party application and then accessing it via another PC on the network. I won't go into a list of the endless bugs and flaws with the design of Vista, because I don't really have to: Vista needs a Service Pack already.

That's my take, but I'd love to hear your reasons for being hesitant: Why aren't you jumping whole hog into the Vistaverse?
