From 2 days I completely lost Windows Mobile and installed Android on NAND 2.2 on my HTC Kaiser. Overall, my observations are positive – not that I have time for in-depth work and research of the seams that start on the phone, etc. but I like at least the idea that there is a normal terminal emulator, that I can stick a top on my phone, ls, iptables, telnet or ssh to do my job normally remotely. I have slight remarks on eating RAM but I believe, that if I drive a SWAP partition into it, things will improve. With the rest of the time, I will study in more detail the init structure of this nonsense to see how many unnecessary things I will remove and whether I will be able to save the startup time..
