Seconded.
And that previous rumor thread was of a MacBook Pro case.
August 4 does make sense, given past release history around that date. But it's a Monday.
Now, if August 4 is indeed the release date, and if Apple's having an event on that date, then we'll have an invitation by the night of 28 July.
This could also mean that the rumored new device coming in the next few months may not be a MacBook type at all, otherwise it would be released on August 4. iPods are generally released in September, so this device could be related to the iPod (iWrite mini-tablet?).
Comparison with the existing MacBook if anyone is interested:
Thanks for that! That's awesome.
