One is fine for a laptop, where I try to keep as few things connected at once as possible (less of a chance of dropping the laptop and destroying the thing plugged into it, like I did with my USB thumb drive). In that rare 1% of cases where I need more than one plug, USB hubs are cheap and easy to come by.
I'm especially interested in playing with one of the new USB-C plugs.
clip-on Bluetooth keyboards for phones or something?
Only keyboard cases I've seen are for iPhones (I'm not a fan of iOS) or the Samsung Galaxy SIII. I would have bought an N4 or N5 if there'd been a keyboard case for it. Same with any of the new Moto or HTC offerings.
I own a first gen Nexus 7. IMO, it's the ideal size for a personal video-watching device--not large enough to be cumbersome but with a big enough screen to make TV show watching thoroughly enjoyable. It's also ideal for reading articles and great at viewing "full web" (non-mobile) pages. The price (under $200) was the main selling point to me, and I really did feel like it was amazing bang for the buck (especially compared to my wife's similarly-priced Kindle Fire).
Lollipop rendered my N7 basically unusable (would randomly shut itself off--mine, luckily, wasn't one of those whose device got caught in the infinite reboot cycle), but Thank God there's Cyanogenmod, where my N7 is a big sluggish but still perfectly functional. The sluggishness would probably have been enough to make me consider buying a replacement, and I'm sad that there isn't one (I will never buy another Samsung mobile device, and I hate the Kindle Fire series).
Ah, well. I'm used to being part of an unpopular and unprofitable niche market--I'm still waiting for someone (anyone) to release a new full QWERTY keyboard phone.

...is that the oil and gas companies were enthusiastic participants in the study, providing the data. Their rationale was one of enlightened self-interest, I'm sure: THEY don't want to get sued if they cause an earthquake, and the USGS analysis will tell them where/how it's safe to drill.
(My source is an interview on either NPR or BBC World News, which I can't find a link to at the moment)
No matter what age you are, if you're at all tech-savvy and security-conscious, Snowden is owed your thanks for this reason alone. (Or from Wikipedia, if you prefer).
Related: There's a widely-circulated conspiracy theory that the NSA has solved P vs. NP and broken RSA (and most other forms of) encryption. The fact that Snowden hasn't leaked any documents confirming this seems to be to be pretty strong evidence that the theory is false.
If you have a procedure with 10 parameters, you probably missed some.
