My experience says otherwise.  I find the uBlox6 and SiRF III have no
trouble in most buildings I am in.  And not on the edge, quite strong.
I do agree that steel and/or tall building are very hard on a GPS
signal, but that is not something I often see.

My experience says otherwise.  Many of the newest GPS chips have
emphasized power saings over receiver sensitivity.  Way more than dB.
For example, I find the SiRF IV to perform very poorly compared to the
SiRF III.
