Nexus 7 owner,

I carry on bike on daily commute.

Alzmer rubber bumper case w screen protectors
inside neoprene sleeve
inside oversized bubble shipping envelope folder over (water and shock protectiion)

Battery Hog (as with practically all devices) ESPECIALLY with GPS on...a car charger cannot keep up.
Very Poor Display in Direct sunlight (as with practically all devices)

Its great to have an internet device when your out and about.

I wish there was a cellular enabled tabled that used an e-ink display....very low power consumption and readable in direct sunlight.

a "rooted" nook simple touch gets close... wifi only reader e-ink reader that can be turned into a web browser and email reader.....WEEKS OF BATTERY...and readable in direct sunlight hmmmmm
