Clinquant, that is a great tool you have there, I take it that it is USB? The problem is that the Google Chromebooks I have seen only have 2 USB ports, I use a USB mouse because I hate touchpads. That means both are eaten up and then you have to get a splitter.
I will second that. If you won't add a keypad, then add 2 more ports on the next generation of Google Chromebooks. I know it is to late to ask for that change now, but next go around would be fantastic.
