I told my director I wanted an Ipad and that Apple TV thing for slide shows for the students. Instead they gave me a Lenovo laptop and no projector. Besides the fact that I can't instruct off of it, it's been a damn good laptop. Has Windows 7 on it, and the only complaint I have is that my palm hits the "mouse area" thing and I'll type an entire paragraph in the middle of another paragraph. Simple cut/paste fixes it, but it is annoying. I will jump on board with Matt and say the Lenovo is the ****.
2 years and tons of pirated music on my cheapo Sony Vaio from wally world, still workin' like a champ. No virus protection, only Spybot Search and Destroy installed on it.
I'm stuck with the PC format for a whole since I've got over 10k invested in PC sign software. That being said PC laptops last me a year at most. Except this last go round I bought a samsung with dual TB hard drives. 2 years and counting and it's been flawless!
