Why an iPAD?
If they are looking to make a "Professional" device then why would anyone believe this to be an iPAD architecture?
The Macbook line is used by many in the professional space for the quality, portability and support of little things like REAL business operating systems (read Windows for business... OSX for graphics/video/audio work). I would love to see an apple-quality device to compete with the Surface... consider it a Macbook Air in a tablet form.
Would definitely be appealing to a large group of users frustrated with the "almost good" solution that an iPAD brings to the professional world.
