[maemo-developers] [maemo-developers] I'd like to help improve boot times...

[From: Aniello Del Sorbo]

I remember starting a thread last year on the ITT forum (that'd be
InternetTabletTalk.org forum) asking
people for how long they kept their tablet on before rebooting.
The answers could help understand if it's worth it or not spending time on
improving the tablet's boot time.
Consider, also, that OS2007 sped up it's boot time quite a lot since
previous OS versions.

The thread is located here:
