MacBook Air! Pretty much the definition of "worlds colliding," this feat is brought to you by Hexxeh, whose most recent mind-warping project put Chrome on an iPad. The platform-mixing maestro says in this case everything works except Bluetooth, owing to a lack of support.

Click the source link for 14 easy steps to turning your svelte laptop into Frankenstein's monster, but sadly, there's no mention of where to buy that hopelessly cute Chrome pillow.
Update: Diligent researchers found the Chrome pillow. Peep it in the second source link. Thanks, Matthew.
