It certainly looks like great value, but having used five different models of eInk Kindle and tried the Sony PRC in a shop about 7 years ago, I'd only buy a tablet for general use, not for reading. Even the earliest eInk screen beats any CRT, LCD, OLED screen for reading a lot. The latest eInk Kindle (Generation 7 Touch) is fabulous.
Re Cloud:
No such thing, it's just the hosting available since 1960s, but now more available via Mobile and Broadband, in diagrams since 1980s we always represented the "Network" outside the premises as a Cloud symbol. This was adopted in diagrams for Internet even before 1992 (when Web sites started).
I certainly do not have the Internet reliability or cap to use "so called" cloud instead of my local server. I can't afford Mobile data at all.
Also security, access and privacy isn't trustworthy on so called Cloud services. I would absolutely not use MS, Google or Amazon for my own material. I'm only prepared to use Amazon's Cloud for stuff I purchase from Amazon.
I don't put very much private stuff on my own hosting, which has known security (we have no idea what Amazon, Google, Microsoft do) and has had far better up time. Curiously Amazon is 2nd best, Google 3rd and Microsoft Drive/Azure a very poor 4th. They ought to know how to do it.
People running a business and not having a mirrored NAS (4 people) or proper server, or cheap cluster and using "Cloud" instead are barking mad. One Administrator in 1000s instead of one in house person away from disaster. Or a local digger. There is a reason why the Data Centre / Cloud Services / Hosting my last employer sold services of had two different fibre routes and a very high capacity Microwave link. How many businesses using so called Cloud have alternate Broadband connection?
