Bought it from a store that shipped from China. They also have tablets that have cellular and higher resolution screens. Runs for $200-300. But I'm not sure I'd spend that much for an offbrand.
At that point I feel I'd just get a Surface or Galaxy Tab Pro S to get the warranty, peace of mind, etc.
Still, a Windows tablet is incredibly useful! Especially for dev work.
I never use the Android side. It's not really up-to-date and I have an Android phone. Definitely don't buy this for Android. :) The Windows side is great since Windows Update keeps it current.
The MiPad2 with Windows 10 looks nice. Really just looks like they copied the iPad. Aluminum body, 5ghz wifi, 2k (?) display. But it's ~$250. More than I want to spend for something without a warranty.
I have a Toshiba Encore 2 10 tablet. But i find it too cumbersome to use, the key board is weird and takes up half the screen in landscape mode. And it feels slow. I think I would like to avoid Atom tablets just for performance aspects
I feel it's one of those items where it makes sense at the right price. At less than $100 it's barely disposable. And you go in expecting a cheap computer. At $200, why would I get that vs. a $200 Acer laptop at Best Buy? (And I don't want a $200 Acer laptop either) At $300, I might as well put it towards a better main computer.
What this has been useful for is those times when I just needed a Windows computer for testing in Edge, etc. But it might also be a gateway drug to deciding if I want to get a Surface for my main computer.
