case closed?
I currently have an android device. I've had one for several years and noticed quite a bit of misinformation in your post.
For one, on my device, I'm able to install quite a large number of apps which allow the use of MS Office formats. There are also quite a large number of apps which allow the use of Open Standard formats (preferable to closed source for good reasons). What this means is that I have the ability to use the same files in the same ways from my mobile device as well as my main laptop with one exception. With my mobile device, I have a smaller screen and I'm mobile.
Another point of contention in your post is how you mentioned having your product available when you get back to your main computer. Do you mean your main computer has synced all of your work while you were away or do you mean having to plug your device in to your main machine, waiting on it to sync and then working.
With my mobile device, there are quite a few apps which allow for wireless syncing on the go. I have the exact same files, same versions of those files, on both my main machine and my mobile device.
In other words, my device works just as well for every usage scenario you've given as the MS Surface Tablet will. Of course, since Android is given away freely and Windows is not, with the same hardware, Android would cost less.
To each his own, pay more if you want but I'll stick with Android.
