This is of significance in my opinion, for users of the latest phones, such as the 'N' and 'E' series which have had so many bugs since their release.
I think alot of users (including myself) were anxious about purchasing the latest and greatest from Nokia due to the issues involved with updating the firmware when/if updates are released.
In recent times Nokia have been great for the phones that 'just work' but not so great for the smartphones, riddled with bugs. Will this new firmware updater help solve things, or give them another excuse to release phones with even more unstable software? Time will tell I guess.
