Thanks for the reply. I am also thinking that a couple of these issues stem from 8.1, and not the Surface or apps themselves. As for Skype, it happened again last night, but with one more complication..
I was using my RT to video call, and had Skype open on my laptop as well (not the app, desktop version). I used my tablet for visuals, and my laptop to type in the message box. I was sent a file, and accepted it on my laptop. Nothing strange here, I do it all the time.
This time, however, the file stopped right before downloading all of it, and Skype on my tablet crashed, just like it had before. I never accepted or declined the file on my tablet, only accepted it on my full W8 laptop. It's a curious situation, and I am not the first to run into this issue. Skype on Windows RT does not have a few features that the full Skype app has, one of which being the ability to send or receive files. (This plays a big role in why the ratings/reviews are not great.)
It's small things like this, and various other idiosyncrasies within different apps/8.1/Windows RT that frustrate me incessantly, and make me think that the RT just isn't as good as it could be. I'm hoping the majority of these are 8.1 issues and will be resolved; my RT has become so laggy and uncooperative lately that it is giving me second thoughts.
A question about the Store - when downloading larger apps, the store tries to install them, then gives me the error "cannot be installed, your internet connection is too slow. try again on a faster network." even though other apps (smaller) download just fine, and my internet runs at a steady 15mb/s. Any way around this? It is keeping me from installing some useful apps.
