Most of the ZDNet column, which you can find here, is extremely accessible to understand for most users. In the few areas it isn't, he notes that this probably won't be clear to most people (including most tech writers...!). but then explains what it means. And most of those techie parts related to something I like about the article -- Ed notes that most articles about Windows 10 only related to the consumer end, which is understandable because it's most of the users, and also most tech writers are consumers, not IT professionals at corporations. But a very large part of the Windows 10 user base is business-related, so he addresses that. It's very valuable to know about and interesting to read -- but if you don't care one whit about such things, it's easy to just skip those parts.
Anyway, it's a good, easy look at Windows 10 today if you've been using it -- or even if you're still thinking about upgrading. What works well, what additions are important, what needs improving, and what's still missing. And how it's different from Windows 7, for all its surface similarities. Overall, he's very positive about Windows 10 (as am I), but it's a good, objective look at things.
