Hey, wow, look here -- more Apple iTablet/iSlate rumors, and this time they're bringing aluminum (unibody?) casing rumors along for the wild ride:

Suppliers for Apple Inc's new tablet computer have begun shipping touchscreen panels and will start delivering aluminum casings for it next month, sources said, implying a second-quarter product launch.

Does aluminum, which was removed from the iPhone with the 2nd gen iPhone 3G, make sense in an iTablet with an HSPA or CDMA radio? Or will that get the plastic finish, and the Wi-Fi only version get the aluminum? That would be two finishes like we heard rumored previously, and would mirror the iPhone/iPod touch model... What do you think?
