From a "amount of information" point of view I think it is usable. The size (7 inch screen) is clumsy, you need two hands. It has a smaller brother with less battery capacity (2 Ah against 4.8 Ah) and a 4.3 inch screen, but I found this (SmartQ V7on Ebay from a Dutch seller (no import duty). It has 256 MB of ram, 2 GB of internal flash memory, a SDHC slot, a full HD HDMI output, WiFi (b/g) and a 600 MHz Arm11 processor. It boots into Android (but a gutted version, andRoc is not stable), into Ubuntu (based upon 9.04) and WinCE. On Android I use a VNC client to control the PC running Rocview, which gives a good response. On Ubuntu I installed OpenJDK java runtime. At this moment I can not load my own plan into RocJ, but that may be due to the huge size of it (700 kB), other plans, like on the picture, open just fine. Response time is good. I paid €177, for which you can not buy a lot of LGB locs, certainly not new.
