Hi guys, I'm planning to buy a skin for ipod touch 4(whenever I get it).I've had a 1st gen touch for 2 years and I know how it scratches,specially the back.I'm considering 4 diff. manufacturers. Gadgetshieldz,bestskinsever,bodyguardz & zagg. I don't mind how complicated the process is,I'll manage putting it on.. I have following 2 major consideration: 1.It should be absolutely clear and invisible.I don't want to mess around with all these pixels I'm paying for... 2.I really love these glass displays in all of apple multitouch devices.Hence the skin should give least of that rubber like feel and more like original. I would seriously appreciate comments from people who have used either all or most of them... I'm considering 1 more option.If I put the skin only on the back and go for a pouch smthng like zagg ultraslim..Will that be a good option?Can all these pouches really be sufficient to protect the screen?
