Currently new devices or unclassified devices are lumped into the Non-Mobile group in the device type report. if you breakdown this non-mobile group by devices you can see that the logic is correctly identifying the non-traditional devices, just not classifying them as a device type. It'd be great if Non-Mobile in both the device and device type report matched, and there was a new group called 'Unclassified Devices'.

Many metrics can be tracked granular to the hour, but visits can only be tracked to the day. Website traffic often spikes around email drops, mentions across social news sites or other spontaneous events. There are other web analytics toolse that do track concurrent visits such as Chartbeat, which also show trending content. Showing concurrent visits that are touching the same pages would also be useful to identify ternding content.
