Yeah it might not be terribly important, but it does leave a bad impression when showcasing the device. I mean, my Magic takes 1min 10sec to get to the SIM-unlock screen. A full fledged Ubuntu *nix takes about 40 sec, iPhone *nix about 42 sec and Samsung 10" wifi picture frame *nix takes about 20 sec.
I have always been wondering whether it's the Dalvik VM that does it, considering that Java applications in general aren't exactly known for their rapid startup times. People who have digged into Dalvik aren't overly impressed when compared to similar technologies: http://www.koushikdutta.com/2009/01/dalvik-vs-mono.html /Casper On 26 Aug., 01:29, "Yusuf Saib (T-Mobile USA)" <yusuf.s...@t- Mobile.com> wrote: > The Android OS takes a long time to boot, particularly on a device > which is much slower than a desktop.
