If you end up ordering the NEC monitor and you already have your own color sensor, you can purchase the download of the Spectraview II software online for $89. I ordered a physical version for $99 last week from B&H, and they shipped out a USB credit-card sized drive to install. But after install, the first dialog was "There is an updated version...", so I ended up immediately reinstalling with the latest download. So after all that, all I ended up with was the serial number, which I assume is the same as you'd get online.

You'll love the NEC. And you can use the ColorNavigator Agent to switch back and forth between different profiles. I have a different ones for onscreen multimedia vs press work, and I'd assume you could have a another super bright one foe email, games, etc, if that became an issue as noted above.
My take is that these "expensive" monitors are actually cheap these days. My 24" Eizo was $2200 back in 2008 while my recent 27" NEC was just $850. But even at top dollar, when you are using it for color critical work (even my bi-yearly print jobs run over $50K each) reducing just one screw up is a bargain.
