Why does it seem like the IS2 has
less information than the regular IS?
This may not be true, if we haven't seen all the screens yet, but the IS2 does not have record temperature screens or an air quality screen. It also doesn't have the supposed "Airport Delays" screen or the "Pollen Reports" that the ad for the LOT8s on twcmediakit.com was talking about.
My assumption is that TWC figures the average viewer couldn't care less about these screens, so developing them would be a waste, but I would think that airport delays and pollen reports would actually be useful to any viewer.
