Imagine you really want to become a regular user of steemit: You won't be able to sit in front of your desktop pc all the time and write your articles. A notebook is a nice thing to use (actually I'm writing this article on such device) but it is quite cumbersome and you usually can't take proper pictures with it. A great alternative to a smartphone is a tablet.
For using it for steemit pretty much everything you need are three things: A long lasting battery, LTE support (you won't always have Wifi) and good camera. While lots of tablets have good batteries these days only few support LTE and even less have a good camera.
I've just bought a tablet which meets all three criterias along with being affordable. I'm talking of the Samsung Galaxy Tab A 10.1 (2016). It has a huge battery that lasts over 18 hours (7300 mAh), LTE support and an 8 MP frontcamera (most tablets only have 5 MP, especially the affordable ones). It comes with a F.19 aperture and by that means is able to take pictures also without perfect light conditions. Anyways, don't expect miracles, but it is doing a proper job.
In Germany it is 250 € right now. I got it during a sale für 199 €! In America the price is pretty much the same, just change the currency in $.
