In a simple Tweet today, 'the Woz' noted that he was wasting some time at Denny's waiting for the local AT&T store to open. Reason? He wants to see if the Nokia Lumia 900 is available for purchase. Of course whether or not he can get one is a separate issue as stores are running low on supply of the flagship Nokia phone, especially in that popular Cyan color. (An alternate reading would be he just wants to see if the Lumia 900 is selling well, but our bet is he just would have called to find that out).
