What Chinese pad do you recommend?

Question

Android

More and more I come to the idea that I need a tablet. But there is one caveat. Yes, that's right, no money, every ten bucks "makes the weather". From this follow the requirements for the price (I look at the devices lying on the shelves for ~ $ 50, but in principle if it's worth it (for example, for the sake of Atom with Win8, on which you can run desktop programs or just one that suits me in all respects at once and is known for reliability, I would tighten the belt and fork out)) and for quality (I really would not want to throw money away on a device that cannot be used without swearing or which will fall apart in a couple of months).
It is clear that "canaries for a penny and to sing in bass" does not happen and you have to sacrifice something. I'm ready to sacrifice, for example, the steepness of the video card - I can do without 3D games and similar pampering on the tablet. On the characteristics of the camera, too, more or less do not care, you can, in principle, without it at all. The color rendition of the screen, in general, is also to hell with it, as long as it can be seen normally and you can read it. WiFi 802.11g is more than enough (although n would in principle be useful purely for compatibility with n-only points if it does not add much to the price). GSM / 3G and GPS modules can be sacrificed if they change the price by more than a few bucks. From the battery, some feats are also not required, and thickness with weight is not a concern.
And here's what you need:

• a removable battery is definitely very desirable, categorically do not care about the thickness and weight
• necessarily a light root of the current version (preferably as a regular feature) and support for the latest versions of alternative firmware (Cyanogen and / or something else like that)
• necessarily USB host and the ability to connect the adapter to a wired Ethernet network through it (to configure routers and the like)
• preferably two MicroSD cards (one to put applications on one, the other purely as a removable drive)
• It is very desirable to have a connector for an external microphone, and not just for headphones
• preferably Bluetooth
• preferably a standard form factor that copies some iPad or Samsung so that cases fit
• I dream of a device with a thin stylus like the Galaxy Note, it is clear that this is hardly worth expecting from budget models, but suddenly ...

Answer 1

You would at least write the options that you looked after.
Well, based on your lack of an option, then you have a direct road to alliexpress (or to another site / store), look for the options that suit you and read, see reviews about them. And be sure to check out the 4pda.ru page, if your device is there, then accordingly there is a sea of ​​​​information, reviews, reviews, firmware, a community of owners to whom you can ask a question, etc.
So good luck with your choice.

Answer 2

The first point of "needs" sweeps aside 95% of the entire tablet market.
About

Atom with Win8, on which you can run desktop programs

I recommend VOYO A1 mini price from $ 130 licensed Win 8.1, but it does not fit the vast majority of your parameters.
Now I use just this one with a fastened keyboard and USB2Ethernet via OTG, and the heavy, outdated and low-playing Eee PC went to sleep peacefully.
There are similar analogues with 3G.
The functionality is enough for any diagnostics / configuration of a PC, routers, etc. (conducted on a laptop without additional expansion cards)
