I have never really wanted a laptop, but I managed to get one from work in a game of chance. I started to find it very useful because I was able to work on the same computer wherever I was. Slow VPN connections were no longer really an issue.
Embracing the laptop experience, I bought a wireless router. As I type this, I'm in my livingroom with no wires at all :) I'm actually enjoying the experience so much that I found myself contemplating purchasing a laptop as my next computer. Maybe even this one.
My real complaint about laptops, the small screen real-estate and keyboard, can be mitigated by simply using a different machine to remote-desktop to it. On a 100 Mbps LAN, it's no different from actually using the console. For some tasks, like storing volumnious amounts of media, you'd still need a stand-alone computer around anyway, so it shouldn't be hard to find a machine to remote-desktop from. Other than that, I think I'm a convert.
Also, touchpads suck ass. That is all.
