Mine is finally downloading the update but slowly. About half way now. I assume it is because so many new machines are contacting the server.
I kept rebooting mine but it didn't do anything. The last time I restarted I noticed a yellow line starting on the page about the update. Just looked and it is rebooting itself. I guess you just have to be patient.
At least others will know it is a time problem connecting and not a problem with the device.
