I'll take any lightweight.
We carry around computers in our pockets. Many people barely use them as phones. We use them as computers. If you think about the future, when you're traveling around, it's great to have a lightweight, small form factor.
My staples are a beautiful pair of black pants, a lightweight coat, a great black heel, and a black cardigan. Everything else is just a topping on my fashion sundae.
I have a specialized racing bike, which is great because it has a solid build, is comfortable to ride, and is lightweight.
In the 1950s, when I was hanging around Sullivan's Gym and the Gramercy Gym, there were fixed fights. Mob guys like Frankie Carbo and Blinky Palermo had taken over the sport; one lightweight champion loaned his title to others at least twice; the welterweight division was a slag heap.
If you believe that the mobile phone is the next supercomputer, which I do, you can imagine a datacenter that is modeled after, literally, hundreds or thousands or millions of mobile phones. They won't have screens on them, but there'll be millions of lightweight mobile-phone processors in the datacenter.
