I ended up with a kde desktop set up that was good.
I used a mini handheld keyboard by Rii, it had a touch pad. There are many different styles of it. But with the customization kde has, I got a pretty fluent set up. It was a full desktop but almost more like android in terms of usage.
It's not that. Or at least you have to reboot into it.
...or can you just load a desktop environment without rebooting... Keeping your apps open...?
