Hm, that's a bit... disappointing. First, Ubuntu for Android claims that it "is a complete desktop with a full range of desktop applications including office, web browsing, email, media and messaging" and "enables high-end Android handsets to run Ubuntu, the world’s favourite free PC desktop operating system". Naturally, then, I took the desktop apps to mean LibreOffice, Firefox, and the rest. Unless Ubuntu have ported all of these to be running on qt5, it is highly misleading. And even if they have, I still want a usable terminal, emacs (the gui version preferably), and so on.
I'm typing this in firefox inside a Debian-based chroot in an android tablet (with a bluetooth keyboard case). It is displayed via VNC, so I can't watch movies and so on, but I have android for those. For actual work, this is in fact good enough for me. I take it when travelling, it weighs almost nothing and its battery lasts all day, and I have used it to prepare presentations (latex beamer), edit documents (latex, libreoffice) and spreadsheets (libreoffice), and even program (python). I have kindle, a nice pdf reader, etc on the android side -- so if I'm only reading, I take it out of the keyboard case and use it as a regular tablet. I also have Firefox on android, but the linux firefox works better for me. And the battery lasts all day. And this tablet is nearly two years old. There is genuine utility in this space.
If Ubuntu would push a co-existence of Android and "normal" Linux, it would be a winner. If it were a full-blown (Xorg-based) Linux, for me it would still be a winner. But from what you say, it is a thing that runs on top of Android (CM10.1) but omits most of the useful stuff in Android, and also omits the useful stuff from Ubuntu. So, frankly, I don't see the point. But I realise it is a work in progress.
