I'm a believer in "if it ain't broke, don't fix it". When Amazon issue an update that THEY think is worth having, they'll send it to me
Obviously if it wasn't worth having then they would not have the 3.0.3 available to the public. Considering the number of bugs it fixes, whether you experience them or not, it is better to be prepared and update, than wait to be without your Kindle due to those bugs, get it fixed/replaced, THEN update it.
Better to save yourself the hassle and just update. The worst that can happen is you never experience the bugs, the best case is you notice a performance increase.
