My comment was more about the administration requiring students to wear a RFID card so the amount of money the school gets can be maximized. This just points out how administrations are gaming the system to get their funding and thus spending less time on figuring out how to teach the children.
I'm an Apple fanboy and I never buy accessories from them. I'd keep an eye on monoprice.com and see when they start selling them. Currently all I could find was thunderbolt to dvi/hdmi/vga. They also had a cable with mini displayport on both end for $4. I don't know if you could use that as a thunderbolt cable.
Usually I'm a big fan of monoprice. Though you can easily find HDMI cables for reasonable prices locally.
When my father upgraded to an HD setup last fall I told him to buy the HDMI cables he needed at Five Below.
Does anyone know what hardware this would run on? While I expect that using Objective-C and GNUStep may get some iPhone developers to try this platform. I wouldn't expect much a lot of code iOS to be portable. The UIKit framework is the core that runs iOS apps, which is something that GNUStep does not have at this point. Is Sony planning on have a touch interface or something more conventional?
I also suggest checking what toner cartridge the laser printer uses. Try to buy one that uses the cartridge that staples/office depot seem to have a decent stock of. That said, most of the cartridges I've bought have been for printers that I got from someone and not bought new. Honestly, I think I've only bought toner 3 times in the last 15 years. Ink is for suckers.
