The 3.3v (XL series) version is a little bit better than that in practice
(~25% lower).  It's still not an ideal family for long lived battery powered
devices.  The coolrunner family is spec'd better for that, but you'd need
level converters if your other hardware isn't 1.8v-2.5v.

These are loads better than the old style gals/pals I used in school.  They
are way more hardy and don't get nearly as hot when pressed.  I'm not sure
why, but I could always get my AMD PAL22V10's to "forget" after a while.
That kind of soured me on programmable logic for a while.  (the cypress
versions I worked with later did work better).  Still, these xilinx
components are quite a bit more reliable for me.  I used the altera parts
before these and they worked handily, but I got irritated with them when
they took out verilog support of the free dev package.  It turns out that I
can get the xilinx parts easier/cheaper anyway.
