Skyn laptop covers

Hi there, we at aspoke.com will print a single skin for you with your own design, if that's what you're looking for. The apple light will shine through the skin!

...and I'm still waiting for a giant floral-print sticker to cover my F-16.

Still waiting for MacSkinz to get their act together.

Form fitting plastic instead of all this sticker junk every one has.

I work with aluminum aircraft structures on a daily basis (I am in the Air Force).
What people usually refer to when they speak of aluminum being weakened by anodizing is actually a reduction in part thickness.
Part of the process of anodizing aluminum involves dipping the part in either sulfuric acid or chromic acid; it is during this process that a negligible layer of aluminum is lost.
This acid bath is necessary for removing the thin layer of aluminum oxide that forms on the surface of the metal. Aluminum oxide is very hard and insoluble, and it interferes with any coating process (including traditional painting).
Some metals (especially the high-strength steels) are susceptible to a condition called hydrogen embrittlement. It is caused by interactions between the metal and the hydrogen ions present in acids. This phenomemon, although serious in ferrous materials, is not a great concern with aluminum and magnesium; aluminum and magnesium are both commonly treated with acid prior to paint application in addition to the chemical milling process at the factory.
In the end, I wouldn't worry about anodized coatings weakening your powerbook. The F-16 contains thousands of anodized aluminum parts, and they all seem to work just fine.
Metallurgy is fun ;-)

for PowerBooks and iBooks, I'm a fan of

When my Powerbook goes out of its warrantee period I will seriously consider getting it anodised. I have contacts who can anodise basically anything (as far as I'm aware) for as little as 10, but I wouldn't trust myself to take apart my Powerbook just at the moment.

I don't see why it would weaken the metal, it's just a surface coating. I've certainly never heard that before.

One more thing that I can't find anywhere on the Web: Re-anodization. My friend that works at the Apple Store swears there are places that will re-anodize the aluminum from your powerbook in colors (Alᠴhe Pink RAZR), but I can find no such place, only the occasional caution that re-anodization weakens the aluminum. Is there anywhere that does such a thing?

Skinit does the same thing, but lets you upload a picture.

However, I'd still opt for the Colorware option, if only I could afford $450 to paint my wife's Powerbook pink! Seriously? $450? I think that's $100 more than when I last checked. When it's available, I'm stoked to see MacSkinz, a custom-fit thin hard shell, but they're not available yet.
