I have one Windows application that I need to use when I travel. I have a Chromebook and wouldn't mind getting a tablet. It seems like a waste and a hassle to get a full laptop just for that one application. While looking for solutions, I came across Citrix Receiver and XenApp. It seems to do the trick, however I don't have a server and don't know how complicated it would be.
The reason I'm not using Remote Desktop or the like is because it's very important that it works and if something happens that requires me to have physical access to my home PC to fix, I could be without the app for days/weeks.
Are there any hosted solutions for this, so that I don't need my own server? Or does anybody have any other ideas?
