Hi, i ordered my black 30gb 5th gen ipod about a week and a half ago.. expecting it soon. Should i invest in any screen protection? i am scared of it getting scratched to hell. Should i get the full works? (the skin that protects EVERYthing ... front,back clickwheel etc).. or should i just get the screen protection one? Im thinking of ordering this: http://www.decalgirl.com/browse.cfm/4,3729.htm is it worth it? its fairly cheap compared to the other ones. will it look cheap/ tacky? thanks.
