I got a laptop this weekend.
I'd been wanting one not because I felt the need to be connected wherever I went, but because I wanted some way to disconnect from my regular computer and still be able to get work done.
I don't know if that makes any sense or not, but I find my desktop computer to sometimes be more of a distraction than anything. With e-mail and Internet, I'm always too tempted to go surfing, or chat, or check message boards and find a I waste a lot of time. I wanted a way to work efficiently without the constant possibility of connecting to the outside world [or inner space, I suppose].
So now I can work on the computer away from the computer, which is sort of ironic, but if it boosts my efficiency it's worth it.
We'll see how it goes. Next I'll need something to separate me from the temptation of using my laptop.
