I was playing on my Asus tablet and ran into Splashtop 2 that allowed me to remotely control my Win 7 laptop from my Android tablet via Wi-Fi with a router. I had a touch pen but it wasn't a fine enough point implement, like what used to exist around 15 years ago. Working on my desktop was dodgy because of the high risk of errors, like inadvertently moving folders around and losing them in others because things "slid" on the screen.

I am thinking about getting a second hard drive in my laptop and installing Windows 8 Pro on it so I can use my Android tablet to run the Metro-UI on my laptop via Splashtop 2.
