I installed Kingston on my Nexus 10 the other night and I was pleasantly surprised. I expected something fairly rudimentary and unpolished. Instead I found a nice suite of tools with a well thought out interface. Of course working with these kinds of tools on a mobile device is anything but fun. It took me several minutes to create a basic spreadsheet with a couple of formulas; something I could do on a desktop in seconds. However, if you find yourself in a position where you have no choice but to work on your mobile device, Kingston provides great tools for the job.
