webos - onward
Is SURFACE the way to to the future or is Android the path to follow?
Also are you aware it is possible to install android on your touchpad? This is assuming you are comfortable tinkering around with your device www.cyanogenmod.com/devices/hp-touchpad
That being said if you are looking to go forward, you can't really go wrong either way. Android is here to stay and keeps getting better as time goes on and new versions are released. Surface hasn't been released and is untested, but the Windows 8 platform is most likely secure in the future,
