Plus:
I don't have to schlep my own computer back and forth whenever I need to do some work. This computer will always be here, in my office, for grades, lesson plans, all the school improvement plan work I do, the time sheets for the school improvement team, etc.

No more wear and tear on my personal Mac. Plus more space to backup everything - I'm a backup freak, I keep everything on my own computer, on the school computer, on the portable hard drive, and on a series of jump drives. Used to backup to disk, then CD, every year. I HATE losing important info!

Minus:
I have to download everything from my personal computer, where I've stored everything for the past year and a half. Where I back everything up. At least I invested in a portable hard drive, and periodically back up anyway.

This new computer doesn't have a port for the LCD projector - how can I show slideshows? Movies? Anything like that???? Now the admins know why I wanted the computer I actually ordered!!!!
