Now let's turn to an area that's not so hot: Windows Home Server. I use Home Server 2011 as my primary repository for backups, as well as for storing benchmarks, downloaded files, and media. WHS 2011 actually worked pretty well with Apple's Time Machine backup tool--until Apple shipped Lion. At that point, the Mac OS Launchpad app displaced the WHS Launchpad (the names and locations were identical), and Microsoft hasn't fixed the problem.
It's still possible to use WHS with Lion, however. One way is simply to use Finder: Click the Go menu, and then click Connect to server. In order for this to work, though, you do need to know the actual IP address of your WHS system.
The other approach is to use root access on the Mac to rename the Mac OS Launchpad, and then to install WHS Launchpad. Unfortunately, doing so merely gives you an easier way to access the server; Time Machine still won't work. I tried a third-party plugin, Orbital Backup for Home Server 2011, but it refused to install on my WHS 2011 system, so that was a no-go. I also considered using a more involved method to back up a Lion system to WHS, but it involved installing a Linux-based virtual machine on the WHS system, at which point my eyes glazed over and I gave up.
The only way I've been able to back up the system reliably is by using a USB hard drive connected to the MacBook Air directly. That's regrettable, but such issues are not uncommon when you're trying to live in a multiplatform world.
I still haven't found an Ultrabook that quite matches the MacBook Air hardware, though the Asus Zenbook UX31E comes close. In any event, I wouldn't buy an Ultrabook today--I'd wait to see what some of the Ivy Bridge hardware looks like when those models begin shipping later this year. Some Ivy Bridge-based Ultrabooks may prove to be very slick packages. My dream system would be something with the same responsive touchpad as the Air, a good keyboard layout, and a 1080p IPS LCD panel--weighing 3 pounds, of course.
Until that as-yet-mythical system ships, I'm quite content to continue using the Sandy Bridge-based MacBook Air. The laptop is light, its battery life is terrific, and it is a pleasure to use on the road. And coming from a pretty hardcore Windows user, that's high praise.
