I've got the
Linx 1010 tablet and love it, I may have mentioned it on some other threads....
As a simple tablet it is great. Windows 10 has a tablet UI that makes the whole screen full of icons, just like Android or iOS, and you navigate with swipe gestures etc.
But you can also switch to desktop mode where it is Windows 10 the same as your desktop PC. It is exactly the same OS. If you have a MS account to log into your PC and use that on the tablet it will have the same wallpaper and synch all the files and folders you select.
So it treats the micro SD card exactly the same as your PC will treat another hard drive. You can choose to install programs on it and if you put all your files on it by default then if, as happened to my old tablet, someone steps on it and smashes it, you can just take the SD card out and have all your files safe and sound, even if they hadn't been backed up to One Drive.
I have a 128gb SD card that cost me £40 on Amazon. I only ever buy from Amazon themselves because there are so many fakes from unknown sellers.
The keyboard is included in this bundle and works great, including a proper trackpad or you can use any bluetooth mouse. I very rarely use the keyboard but it's nice if and when you want to use it. Be warned, the keyboard is quite heavy as it needs to counterbalance the tablet itself.
Speakers are okay, but not that powerful so in a noisy environment you might struggle to hear them.
And if you want you can plug in a external monitor and a full size keyboard and mouse and use it as a dual screen PC. It has three USB (2 full size, 1 micro) and a micro HDMI out. You're not going to play a top spec 3D video game at 70 fps but you can plug in a USB XBox controller and play lots of games perfectly well, there are videos on Youtube showing people doing this. I can play three HD videos at the same time in three windows and open Word and type a letter, so it's perfectly capable performance wise.
And if you just want to use it as a simple tablet it happily does just that. If you have a miracast equipped TV you can sit on the sofa and play a movie or a game on your big screen TV.
