when i type a line say
Happy new
and then <backspace><backspace> and then retype
the old characters stay around until i type 3 or 4 characters.
This is very disorienting.

This happens when vim is in "vi compatible" mode; I'm not sure exactly which option controls the behaviour, probably ":set backspace".
Doing ":set nocompatible" will make it behave as you expect; if you don't have expectations like that, doing ":set nocompatible" is probably a good thing.
