I'm happy to hear about the Wifi. The Pandora's wifi wasn't the greatest at the beginning, but after some patches and especially when I turn off power management it works serviceably, though I usually only manage to get around 1.5 - 2 Mb/s through it.
I'm looking forward to having faster speeds and access to 5Ghz, even if the chip doesn't support 802.11ac.
It'd also be interesting to be able to play with 802.11s and try out mesh networking.
Better cooling is also a plus.
