I use mine for:
-internet browsing
-reading books, magazines & news (especially when waiting somewhere like a doctors office, dmv, etc )
-social networks
-shopping
-as a GPS in my car since it has a nice big screen and they make car mounts for tablets
-playing games
-I've been using apps to find colors that I want to paint my rooms and/or to re-arrange my furniture
-as a TV Remote (you have to buy an app and device to plug into the tablet, mine's an iPad and I can create a custom remote with the app on my iPad and use it to control my TV)
-I have apps for medical emergencies for people and pets where you can get walk through on CPR and other things (my tablet, if not on yet, will boot up MUCH quicker than my laptop or desktop)
-Sometimes I'll use it to view Youtube and other videos, pics, etc...to beam to my TV
-Recipes - finding and storing recipes
-I several cloud drive apps such as Box, Dropbox, and Google Drive to save PDF's of tons of pc tips and tricks and how to fix things when something goes wrong with my pc. If my pc isn't working or booting, etc, I can try to find a solution either on the web or by going through the files I loaded to my cloud drive. I can access these files anywhere as long as I have wifi or I also have a hotspot on my phone, so I can connect my tablet to the internet through my phone if need be.
...any many more uses
