I've been following the project since it was first announced, and while it's interesting, I don't find it particularly useful... I mean, I got a laptop for its mobility, I knew I was sacrificing a bit of graphics performance (although these days the performance loss compared to desktops is unsubstantial). I also don't want a device bigger than my whole computer, with its own power source, sitting on my desk...
As for extending the life of old laptops, well, laptops get old and cheap so fast these days that it's not worth it - the difference between a Quadro FX 770M and FX 880M (which are what, 1-2 years apart), for example, is more than 50% in performance...
I have a laptop as my only computer, and I would love to eliminate its largest flaw relative to a desktop machine. Not to say that you're wrong, just that I think there's a market for something docklike as more and more people have only a laptop.
Agreed. I bought a cheap laptop when my previous computers hard drive failed. Now I have more money, but I don't want to buy a desktop just to play games and then never use my perfectly functioning laptop.
