I'm sitting in a line right now for school (my registration got screwed up and the line is like insane - I've been here for two and a half hours). I didn't have it powered up until maybe 30 minutes ago, when I decided to say, "F it, I want to check my mail and do something other than read the book I brought with me. The only downside, this douche in line near me who has been staring at my chest for the last 90 minutes tried to use my BlackBook as a entry point to start his pick-up line and I was forced to make polite conversation (this guy is just really, really gross - and I'm just not in the mood today).
I used to take my old VAIO with me when I could manage the weight. It had a 16" screen and weighed 8.5 lbs before adding the brick of a power adaptor (another two lbs, easy and that's if I didn't bring an extra battery) and I weigh like 100 lb so lugging around 30% of my body weight (once books, a purse, essentials were added) was not always ideal. But this computer? This computer I'm taking with me everywhere. Especially since the messenger bag I bought last year came with a built in laptop compartment (and it's a Tumi case - so it's quality on top of that).
