[Nexus 7 Accessories] pokey9000:
I've gone through a few BT keyboards with Android tablets over the last couple of years, and I think I've found the perfect one for the N7:

Perixx PERIBOARD-805, $30 at Amazon

It folds to about 6x3.5" and about 1/2" thick, just a little smaller than the N7's active screen area and about as thick as my landscape stand case when folded. When unfolded, it's kind of small compared to a fullsize or even a standard laptop keyboard, but is still easy to touch type on. The split down the middle is a little awkward at first since some of the keys down the middle have been stretched to fill the gap, but not a problem after a few minutes. It's a full laptop style layout similar to the Apple tenkeyless keyboards, with F1-F10, two sets of CTRL and ALT, ~, ESC, and \ in the right places. The arrow buttons are wedged between "/" and right Shift which looks funny but hasn't been a problem. The FN button also activates a bunch of Android and iOS specific keys, like media/volume controls, lock, wake, home, and search.

Everything seems to work as expected in a terminal (AirTerm and ConnectBot) except I can't get the PGUP/PGDN to work in the terminal (FN-arrow up and down), though they work fine in Google Drive. Not the end of the world, and probably something that editing the keymap can fix.

Keys have decent travel (1.35mm I measured) with a sharp tact for something so cheap, and use a scissor mechanism so they don't wobble much at all. The caps aren't curved, which is the trend for chiclet keyboards. It flexes a tiny bit if you pound on it, but much less than many laptops I've used.

It has two buttons on the inside right: one to power on/off, and one for pairing. You hold the power button for 3 seconds to power it on, then the battery and BT LEDs blink a few times to let you know it's alive. Turning it off is done by holding it for a second or two, but there's no indication that it turned off other than the dropped connection on the N7. I'm not sure if there's an auto power off or how long the battery should last as the manual kind of sucks and I've only had it for a day. It does not turn off when you close it, but if it's like most BT keyboards I've used it sips power until you are actively using it so it might not matter.

It's powered by an internal Li-Ion pack, and charges with micro USB. Not sure on battery life yet, but it's nice to know I don't need to carry an extra charger or AAAs. It ships with a short USB-A to micro USB cable that most of us probably will never open, but a nice touch anyway. It can be charged with the case open or closed, and the charging point is right near the ESC key so that it faces away if you want to charge it while using it.

Unfolded, the case rests on 8 feet: the four surrounding the hinge are bumps in the plastic, and the ones at the corners are rubber to prevent slipping on a desk. When folded, the case has a glossy hex pattern on top of black matte plastic, which is a nice change from plain black gadgets while not being too flashy. It feels sturdy enough to take some abuse at the bottom of a backpack.

Anyway, if none of the other keyboard options are doing it for you, and you want something very portable, get one of these.
