Earlier quoted context omitted.
It comes down what you actually want to do. My time spent on the iPad was defined by what I couldn't do, and it was extremely frustrating, I ended up not doing it instead of go getting the laptop from across the house. Windows is not refined nor optimized for tablet use by any measure, but it actually does the job, instead of showing a cute and extremely refined middle finger half the time. The breaking point for me…
I don’t know about anyone else but my expectations are not for my iPad to be suitable for serious development work or whatever. I want to read books and magazines, surf the Web, and watch videos. And for that it’s arguably better than a laptop. At least I find myself using it for those things much more.
Youtube playback would stop everytime another video starts playing somewhere (additional fun when it's just a video ad that actually had no sound in the first place).
SMB file management is still an afterthought, so you end up needing a plex server dealing with all the complexity the iPad can't deal with.
Browsing is the same, outside of the Safari limitation, extensions are few and tab management a pain in general.
For books and magazine it's kinda the same. It works fine for light use. It becomes frustrating if it's something you actually care about.
In the end, I realized I actually care less about visual polish and more about having complete functionalities, at the price of dealing with Windows and managing a computer instead of an appliance.
