Thank you,

My point wasn't to criticize but to check out what could be done to speed up
this component in order to have a smaller boot time, and with a different screen.

Since the resources are quite low in comparison to a modern computer
maybe it needs some low-resource-computer specific optimizations.

I'm actually considering studying e's libraries in order to create some
replacements for the most common applications.

I think it's quite intolerable that in idle the main applications (at
least) aren't near instantaneous, and if e's the way to go, then e-like
apps should be written.
