As I understand it, only UHF channels 52-68 are being repurposed for LTE networks.

...the only models that can do 850MHz UMTS are the ones intended for Australia

Even then, many Australian phones do 850 MHz and 2100 MHz, but AT&T uses 850 and 1900, so the phone won't work everywhere.

I was helping a friend set up her new computer.

She opened up Internet Explorer and noticed the default search engine was Bing.

She tried to change the default search engine to Google.

Her: Why is it taking so long to change the search engine?
Me: Why not just download Google Chrome?

Problem solved. :-)

Agree, but it's trivial to adapt to.

~/.inputrc
  set completion-ignore-case On

~/.zshrc
  zstyle ':completion:*' matcher-list '' 'm:{a-zA-Z}={A-Za-z}'

I'd suggest putting /dev, /proc, and /sys together into /system. /dev becomes /system/devices, /proc becomes /system/processes (actually I'd be OK with keeping the abbreviation and using /system/proc), and /sys becomes...

... /system/kernel?

There are wallets that also have a coin section.

It's just there's not many of them, or the coin pocket is very small.

In countries where $1 or $2 are coins, and tipping isn't expected, having such a wallet is very handy.

Doubtful. A lot of prices end in .99 not because that's the store's actual cost, but because apparently many customers think 4.99 is $4, not $5.

Australia got rid of the 1c coin years ago. Prices that used to end in .99 now end in .95, not .00.

A big advantage of $1 and $2 being bills is you can get away with carrying only a money clip. And a lot of wallets don't have coin pouches either.

In Australia, where we have $1 and $2 coins, the coins add considerably to the thickness and weight of my wallet. And there are many vending machines that only accept coins, so you have to carry $5-$10 in change to be safe. With a $1 bill, vending machines would only need to accept notes, and should accept higher denominations too.
