A couple of months ago I'd gotten sufficiently fed up with Android that, when my Android tablet decided to reset itself again, a week or so before I was going on a trip, at the same time that Fry's had an Ematic Win10 tablet on sale, that I'd give Windows tablets a chance. The one I bought had 32GB of flash (plus a microSD card slot), and had 15.9GB of that free. I ran Windows Update, which told me that Anniversary Update was available and needed 16GB of free space; turns out that doesn't mean 15.9, nor 16, nor 16 with an empty 64GB SD card - I had to drag&drop enough different things over to the SD card to get about 18-19GB free on the built-in to get the update to run. But once it had enough space it ran cleanly.
The latest outrage from MS is that the email account I registered it with had the form "email@example.com", and MS has decided that to protect me from losing access to the account if I forget the password, they need to VERIFY that by sending it an email, which never arrives because they're confused by the "+tag" in the name field, so when I tried to add a different email by answering a bunch of bogus security questions with the same answers as last time, they sent the "VERIFICATION" email to the new address, I clicked on it, and the first thing it does is demand that I re-verify it by having them send a code to the old address. I have not given them a phone number to call, since I have no interest in giving them my real information; I'm tempted to borrow a burner for that, or see if they can send the code by audio to a VOIP system or something.
(That's not even counting that Windows 10 tablet mode is pretty lame, and works much better with a keyboard, and the nice ergonomically designed keyboard that came with the tablet died after about a month, but that's more a symptom of what you get for $70 on sale.)
