I don't think it's really worth the faff to do it unless it fixes any specific bugs you're encountering.

I'm just going to wait until the next update drops OTA which'll include this one. Someone mentioned last week of Feb/1st week of March.

Nokia timescales probably means mid-March but waiting a couple of weeks won't harm you and what's the point in installing an update that you'll either not notice or may speed up/slow down your phone -sorry, Mobile Computer- slightly (depending on whose post your read).
