Haven't used virtualbox. Just tried once. If I install the Leste image what parameters of the machine I should put for the virtualbox? Like do I check N900 specs and put those with screen resolution, ram, cpu etc. to get the right experience? I remember I needed to choose those kinds of stuff when I once installed Skywavelinux on virtualbox.

I think I subconsciously implemented on my question a feeling of being puzzled why I haven't heard anyone trying the Dooble with Leste. Like "there sure is someone who has already tried and will answer" kind of thing.
