I'm bed bound a lot and it allows me to keep in touch with the world. It's so much lighter then my lap top and boots up faster too. When I'm done surfing the web, I can go to sleep to the music I have loaded on it.
I use mine for a lot of things. Doing stuff for my work and lots of research, social media, playing games, watching movies, TV series and anime, reading ebooks and manga, paying my bills, ordering food, and a lot, lot more!
I use the mine for a lot of things too, but mainly for watching videos (an 7 inches iRulu Tablet)... unfortunately in my country I can't have full access to wifi or bluetooth because there's not almost exist... so I'm missing all the strength of internet and email connections... Another use is as a calendar/agenda and notebook, very useful because its size. It has little screen size for a good spreadshet/document visualization but I have used it for. Because I "broke" the internal SDCard and I have to use an external one, I can't save or rename files but it's useful anyway...
I use my tab for literacy tutoring. Its light weight makes it ideal, and there are lots of excellent free apps for working with adult ESL students. At home I play Words With Friends and keep it handy for those questions that need Google.
