I bought it for the rare occasion that I absolutely need it, but my home network is already quite friendly to the drive-less little machine.
Over the last couple of years, I have archived disc images and license keys for software I have purchased onto a RAID5 attached to my desktop. Makes it really easy if and when I need to reinstall software on the desktop since the only disc I need is the OS install disc, if that (as I have a copy of the OS installer sitting on a second partition).
I also have the software repository accessible under my account across the network, so if I need to install something like Office, I can mount the image remotely and just install.
At this point, I rarely even use the DVD drive in my desktop, let alone a laptop which has full access to my archives wirelessly and does a lot less heavy lifting.
