Okay, so I was all set to go out and buy an 867 tibook, but then Apple has the audacity to give me more choices and bring forth the mighty 12. I couldnt really care less about airport extreme (I dont use a wireless network) or built in bluetooth (no bluetooth products), but its the new skin that Im interested in, namely the Aluminum (a.k.a. non chipping) case. I mean, Ive heard stories about the tibooks titanium paint chipping away and in my mind I have surmised that a stray dust particle brushing against its hull will cause scratching or chipping. So now I am deciding between the 12 and the 15. I am still very interested in the tibook, but, this being my first powerbook, I want it to last a while (at least a year or more) without the thing looking like a rusted VW muffler. So, what Im asking is exactly how hard is it to scratch or chip the older tibooks? I dont plan on dropkicking it anytime soon, but normal wear (e.g. sitting on desk, bring home, slight pounding of keys after being outsniped in MOH, repeat ) is expected. And also as a bonus question: whats the best protective product out there for it? Is there a thin see through plastic like casing that slips over it that doesnt deprive it of its Appleicious beauty, but protects its skin? Thanks for any replies.
