My wife currently uses an old 10" Galaxy Tablet, running an older version of Android. Battery life is getting poor, it's just not running well in general (despite a recent factory reset), etc. She's not happy with it, and we're planning on getting something newer/better. The Galaxy Tab S3 is the current version in the 10" size that she wants, but even on sale is $450, which seems over-priced for the hardware and OS. I have a Microsoft Surface 3 (the older, 10" size, Windows 8.0, which I love), so thought about getting her a Windows device. Lenovo is about to come out with a "Tablet 10" which is basically a 10" Microsoft Surface, smaller/lighter. CPU not quite as fast as a Surface Pro, but should be fine for general purposes. 4gb RAM, 128 eMMC, Windows 10 Pro, keyboard included. A SP4 would be more powerful, but the smaller size is more important. But the questions I'm asking pertain to the Surface Pro 4, so thought I'd ask here. She uses her tablet a lot to read Kindle Books, shop at Amazon, read Library books through Overdrive, Facebook, Instagram, general web browsing, etc. As I've read reviews of Windows-based "Apps" for these various functions, they're not particularly encouraging. Often 40-50% 1 star reviews. So I'm wondering if she would be happier with another (overpriced) Galaxy Tablet, rather than being unhappy with how a Windows 10 PC handles Kindle, Amazon, etc., in its Tablet mode. Input appreciated, for those of you who use your Surface with this type of 'Android Tablet' functionality - what apps do you use, do they work as well as their Android equivalent? Kindle is crucial - if this can't be handled well, that's a deal-killer right there. Any other thoughts?
