I have an Galaxy S2 tablet. I bought it a few years back after getting sick of the iOS updates that sucked on the ipads. I will say that even after 3+ years - it is as fast as it was the day I bought it. No issues like the iPads have will gradual slow downs with OS upgrades.
I looked at getting the S4 - but damn, if they are not damn expensive. I then found that HP Chromebook X2. I had never heard of it for a while… HP really doesn’t advertise it clearly - when you first see it online, it’s hard to tell that it is actually a tablet with a detachable keyboard - just like the Microsoft Surface tablets. When you first look at the description - you think it is just a normal Chromebook.
Except - the detachable keyboard is included. You don’t have to spend about $100-$130 for the keyboard.
I got mine for $399 - at Best Buy. Unfortunately, Best Buy discontinued the model over the summer. But, a few places still sell them. I think they are $479 on Amazon.
It’s actually a full computer, with a keyboard and trackpad. You can also plug in a mouse, if you want to. I have a USB Type A mouse I tried - but I had to use a converter to turn it into USB-C. But, a blue tooth mouse would solve that issue. Anyway - it is a full Chromebook.
Or, do what I do… I never plug in the keyboard because I bought it to use as a tablet 100% of the time. You can use many Android apps on a Chromebook as well. It works fantastic.
The ONLY negative I see is that it is a 12" tablet. So, it is a bit bigger. And, there is only ONE case made for it - They sell it on Amazon. If you click on the link that @godfrey just posted - it will take you to the links of where the tablet is sold, and where the case is sold as well. I posted that info on that other $200-$300 Android Tablet thread.
I am VERY happy - and, I got it for less money than the S4 tab. And, I have the full version of Chrome - not the slimmed down android version. Plus, it has a real keyboard, if you ever need one. The S4 keyboard works - but is probably not that comfortable to type on.
