Just my 2c.
I'm not a programmer, unfortunately, but I'm a fond user of NIT's (and Nokia communicators, btw).
My device is lovingly kept in shape, sporting an old but dependable chinook firmware, which prevents it from the reported problems of diablo, and gives me no thoughts. I bring it to work, and in journeys, and back home, and it keeps working as a faithful net donkey.
I do monthly backups of the rootfs, the debian chroot and the data fs (fat) and so I'm protected against possible glitches. Sudden full discharges happen even if rarely, and it's generally some flash app in the browser kept running.

Life's good

I bet you're suffering from the APPITGM syndrome (Anticipated Post-Partuum Depression In The Geek Male), Relax, enjoy, and when the new baby has settled home, consider a downgrading - it could be the right move.
