If you want something that stands out of the crowd, then you might want to take a look at the Jolla Tablet http://jolla.com/tablet/. It won the Best tablet award at this years Mobile World Congress. I've been using a Jolla smartphone and really like it. It doesn't spy on me, I can get root from the settings, it has a command line shell + SSH built in and it runs Linux.
Jolla's Sailfish OS is based on the Maemo/Meego line. They've built a really nice user interface on top of it and it's partly open source. The UI is based on swiping gestures, so it takes a few minutes to learn to use it, but after that it's really swift and nice. They also have an Android VM, so you can run Andoroid apps on it if you want. No Google Play store though, but I believe you can enable it yourself if you want. If you want apps outside the official store, you can add additional repositories to the phone.
Jolla also listens to its users. You can log in at http://together.jolla.com/ to leave bug reports, feature ideas and ask advice from the community and Jolla sailors. The OS gets regular updates which add features and squish bugs, so my phone is actually a lot better now than when I bought it. The specs are more modest than the current Android flagship models, but the OS is much lighter so doesn't need that much processing power to run well. The price tag is pretty nice too.
Have a look, try it out. They're just about to start shipping.
