Actually MiniUSB is more fragile:

http://en.wikipedia.org/wiki/MiniUSB#Durability

The newer Micro-USB receptacles are designed to allow up to 10,000 cycles of insertion and removal between the receptacle and plug, compared to 1500 for the standard USB and 5000 for the Mini-USB receptacle. This is accomplished by adding a locking device and by moving the leaf-spring connector from the jack to the plug, so that the most-stressed part is on the cable side of the connection. This change was made so that the connector on the less expensive cable would bear the most wear instead of the more expensive micro-USB device.

Considering that you can't draw more than 500ma from most USB ports without them tripping on you, it can't be THAT power-hungry.

I suspect that it uses a lot of power for USB, so won't run from a host-powered USB hub (which take one 100ma power slot for themself, and with at least one taken by every device plugged into it, doesn't leave much).

Comment Re:We need a hybrid system maybe ipv6 outside ipv4 (Score 2, Informative) 270

Private IPv6 IP ranges have been designated:

Link local addresses: fe80::* - automatically self-assigned by an IPv6 device, exist even if the device has a global address
Unique local addresses: fc00::* / fd00::* - manually assigned, globally unique but not routable on the internet

So it should be:
sqrt(i^4) = sqrt(1)
+/- i^2 = +/- 1
sqrt(+/- i^2) = sqrt(+/- 1)
what's sqrt( - i^2) ? I'm guessing: sqrt( - i^2 ) = sqrt( -1 ) * sqrt( i^2 ) = +/- i * +/- i = +/- 1?
And sqrt(+/- 1) is either +/- 1 or +/- i
so you get:
+/- 1 = +/- 1 or +/- i?

Now I'm confused.
