Love this monitor. It gives you the space to do side-by-side work without taking up extra desk space as well as expand one window when needed (like in an eclipse debugging session with a smaller Android emulator on the side.)
I agree that 30" is just too big - gotta turn my head a bunch if it's on a normal-sized desk
NOTE: This monitor is on sale for $649 today - use code RDSVHG$9FHDJ44
I've been recording and posting my lectures at JHU using Camtasia for many years...
I whiteboard using a graphics tablet (Wacom Bamboo fun, drawing ink notes on Evernote). I write code examples on the fly in Eclipse (and if Android apps, run them in an emulator or use droid@screen to mirror). I surf to websites. When I rarely have slides, I show them. Everything I say (using a headset mic) and do is recorded using Camtasia. After class I do some minor edits and post the videos and example code from the class on the course website after class.
Much less expensive than a smartboard (even moreso if you use alternate recording software), and the students love it (almost everyone comments on it in the evals)
I'm a little surprised that the students still come to class... I suspect it's because they like being able to ask questions and interact with the other students.
