Not sure that partitions help here. If we are taking personal box/laptop /home is the only
thing I care about and it'll have all the disk space as well.

OK, then you won't mind if I rm -rf /usr on your machine.  :-)

Try:  du -shc /var /usr /home
(There's also the root stuff not in those, but it's harder to measure that.)
You may be surprised at how much is in /var and /usr.

My home dir contains ~82 Gb. Compared to that, /usr and /var don't contain a lot (under 10gb).
I'm sure most people are similar, hence my comment.

10GB is still a big important chunk of disk, whether the rest is 20GB or 82GB.  Checking 
it separately *will* speed up each check, and separating it into a separate filesystem will 
make sure that errors on one part won't mess up the other part.

(Come to think of it, I suspect that the fsck speed is more dependent on number of files 
than data size, though I don't know for sure.)
