Hi. You are right about the variable performance of Linux chroot on different android devices. The only android devices I've ever owned are the Samsung Galaxy Note 1 and 2 so my experence is rather limited. While I found, on the Galaxy Note 1, Unity desktop environment to be a bit sluggish, LXDE worked fine. Both worked nicely on GN2. Synaptics and wxMaxima work fine on GN1. Also on the GN2 Synaptics, wxMaxima, TeXMaker and Okular work with no major problem. I haven't tried all these on GN1. Clearly native GUI should have superior preformance than VNC but, surprisingly, the response using VNC is very good on these devices. Have you tried Jump VNC? I think it is quite responsive. In general, I think you are better off using an android based browser instead of that found on linux on android but there are always trade offs. Also, I have a n9. It is a beautiful device too, but, I really wanted one with a HWKB. I would probably have not gotten the GN if the N950 was generally available. At least the Galaxy Note has a stylus like my beloved N900!
