The Peg1 here is my main computer at the moment, I'll probably get a
Peg2 within a month but the Peg1 will still be used.

The only real problem I have with the current age-old OF is that about
every second boot is aborted due to some spurious signals from the
mouse, causing the dreaded "keycode xyz has no translation" or
similar. Sometimes I need to reboot 2 or 3 times in a row, this is
quite annoying. And when demoing stuff it's highly embarrassing to
explain why this extremely simple thing hasn't been fixed after
several years.
