I currently use LogMeIn to help my grandma with her computer woes. I only log in remotely about once per month, and only for a few minutes - so a pay as you go option would be perfect for me.

I tried copilot - but it failed utterly and miserably on two points:

  - DPI. My grandmother's computer has a high DPI setting, so she can read menus/buttons. When connecting from my local computer, copilot just couldn't handle the DPI difference (appearently).

  - Windows 8/Metro. When my grandma was stuck in metro, I couldn't connect remotely. Which sort of defeated the purpose of the tool.
