Axiotron Modbook upgrade: not quite 2 minutes, but overnight ain't bad
If you have $1,149 to spend, TechRestore can convert your MacBook into an Axiotron ModBook overnight during the work-week. They've put together a little stop-motion video, even, to show you how it's done.
The $1,149 price is good through March 6. Overnight delivery options are an extra $29 to $99, depending on whether you ship it yourself to them, drop it off at a shipping center, or have it picked up.
