T23 display/energy consumption query

[findrivr]

Everyone knows how nice it is to have all of that extra image detail that comes with a sxga display on the T series TP's.
My question then is: Does all of this extra detail come at an energy price.
In other words given all the same specs across the board, would 2 otherwise identically configured T23s [or any T series] , one with 14" xga vs. 14" sxga, waste a LiIon battery down in the same amount of time. Or, is the difference neglible; meaning less than 5 minutes in a cycle.
The answer to this may sway my decision to pursue a good used T23 xga vs. sxga.
Comments or advice.
Thanks,
Patrick

PS: Anyone know of a list of model numbers 2647 & 2648 that identify units with sxga?

The difference is negligible and the answer to the above is in the FAQ.
