The Logitech Rugged Combo 2 keyboard case for the iPad is probably not something you want to buy. It is too big for most. It's very, very tough, surrounding the device in a huge plastic block that feels like it could protect the glass inside of almost anything. (Logitech says it's good for a fall of up to four feet, but I bet you could handle more). Actually, you can not buy it anyway; It is designed for the educational market.
But I'm here to tell you that it's fascinating. The spill-proof keyboard is not connected via Bluetooth, but through a custom smart connector developed by Logitech, which passes to the Lightning port inside the housing. The keyboard is therefore removable (it is connected by a strong magnet) and can be replaced with a simple cover.
The thing is lifted through a support on the back. That means that, when the keyboard is connected, it basically looks like a large and large Surface Pro.
Apple says teachers asked for a keyboard option other than Bluetooth for the classrooms, so they did not have to waste time pairing them with iPads. That makes sense! It makes so much sense that you want the iPad to have a smart keyboard connector.
The case itself is very difficult to take off (we can not do it), which is by design: if children never take it out of the case, they are less likely to break their iPads. It also has a lightning step connector. Perhaps the most pragmatic touch is a small clear window below the surface support. That's there because schools put stickers on the back of the iPad to identify them.
Schools will be able to purchase the Rugged Combo 2 case this summer.
