Cool (I'm on mine now), and it's definately useful (use mine at work, use it for school, etc.). It was the logical progression from the original room-sized mainframes to the home PC to this. It could use some improvements (though that can be said of anything): controlling heat is a problem, for one, and I'd like to see flash memory become the standard instead of the traditional hard drives we have now.
The bad thing about laptops is that, as Marius had alluded to, they've made computers even more of a 'disposable'; you can't just upgrade parts as easily as you would your home PC (then again, if you get a pre-packaged Dell home PC from somewhere like Best Buy, I guess you can't really upgrade that much, either, so there you go. Best to build them from the ground up, if you have the means to do so). Recycling is available, but few people know where to go nor care to take the time to go there.
