This really is no joke, as much as one would like it to be.
I think there are a lot of generalities being thrown around as well.
Quite honestly, people look at one thing and the don't see the usefulness of it, in a practical since. Then they generalize it as that is how they will always do a task, when that really isn't the case. It's a helpful tool to get a job done more efficiently. Such as, a Word Doc that you have on Skydrive that you realize sitting in a cab, at lunch whatever, you either A.) Don't have your Laptop/Tablet with you, but you do have your phone, easy, add, edit delete what you want then you don't have to try and remember it later.
There are vast possibilities.
So I created a Recipe in One Note on my phone, was it easy? no, but it worked, and it was when the notions hit me, I had a shopping list made out of the recipe at the same time and when I got to the store, I didn't have to try and remember it, Also, i had checks I could mark off as I went. I didn't have to try and remember it, it was right there
I got home, pulled it up on my desktop and completed and fleshed it out, then made it.
I had all the stuff I needed and didn't forget anything,,, this is just one simple example, and by no means even a very good one. But an example that was extremely useful none the less, and I hate writing on paper and putting it in my pocket then have to retype it,,, in this case most of it was already done. I didn't have to try and recreate anything or re-remember anything.
The point is, many people are missing the usefulness of the tools that are provided on a WinPhone with Skydrive and Office Access. Especially when you are in a location that doesn't provide an environment suited for pulling out a Laptop/Tablet.
These things Phones and Tablets are tools to be used in the capacity they are designed, not a replacement for everything you have. I think people loose sight of that fact and over generalize the usefulness and then write them off as useless.
