You come across as someone that went into the Surface not wanting to like it and you found a bunch of reasons from reasonable to erroneous not to like it. Does it seriously bother you what other people think about the devices you use?
Word doesn’t save your work unless you click on a 3.5” disk icon regularly.
This is an example of one of your contrived reasons. Word auto-saves at a user-definable interval. It also creates AutoRecover files at a regular interval. I've had situations like power outages hard shutdown my computer and AutoRecover restores them up to the second.

Some things are saved on SkyDrive, some on the local disk, which isn’t automatically backed up either. So now I am forced to be aware of this leaky abstraction, to manage the remote and local state and at this point I might as well just have a MacBook Air and be done with it.
Just buy a MacBook Air because that's obviously what you want. This is another contrived reason. Backing up the local and remote (Skydrive) data on your Surface RT is pretty darned easy to set it and forget it:
