My Lonely Mouse
This is a hardware thing, but my Samsung Chromebook doesn't have Bluetooth. I can't use my mouse. The touchpad is fine (although I can't count the number of times I've accidentally right-clicked because I'm too lazy to lift my fingers off of it). Somewhere I've got a USB stick at home that I now have a use for. The trick is finding it. Let's chalk this up as a problem for old-school users... unless you start to think about Bluetooth headsets....
When I get questions from teachers about how to do something, I usually answer with a video. Evidently, there's a Chrome app for screen-shots, but not for video recording of the desktop. So for now I'll either have to stick with my other laptop or use my a webcam aimed at my screen.
For a bit I was worried that I couldn't split the screen and show two tabs at the same time. Turns out that there are keyboard shortcuts for that.
I'm still learning about the Google Chromebook, but I can tell you that the Chromebook experience isn't about the device: it's about what you do with it.
What are you doing with your Chromebook?
