i think to be fair... it will depend on each user...
as for the sticky roller scroll ball... maybe some people just clean it after using... maybe some people just have very clean fingers... and maybe some just pure luck and it never fails for a long time...unlucky for some of us i guess...
as for me... i do not prefer wireless whether it is an apple mouse or a normal pc mouse... the reason... i am a butter finger... i'll most probably risk dropping the mouse within 1 week of use...i prefer the wires mouse....cos at least there is a cord for it to hang by if i do eventually drop it...
and i don't understand why gamers want wireless mouse...it is heavy, won't it affect their gaming...i know some of my gaming friends like ultra light and sensitive high dpi mouse...and the apple mouse isn't any of the both especially the wireless... just my opinion...
as for the bluetooth.. i never heard of any signal interference... some people told me their mouse doesn't work after their computer fall into sleep... normally they just need to give it a click after waking from sleep and give it 3 or 4 seconds before starting to move the mouse...i think this is to give it a moment to re-establish the bluetooth link again...
as i say it really depends on the user... some might think that it is expensive and serve no purpose... but some might like it for it's design, looks and functionality....
don't pry open the mouse... you'll most probably end up buying a new one...if you keep it maintained nicely i think an apple mouse will last as long as a normal pc mouse... the only thing that i can do nothing about is the high price

...again the price thing is just my opinion... RM199 is a bit too rich for my blood.... i'd rather have a razer copperhead mouse....
