Circuitry just ain't there as ElBrio points out, so agreed it's a no-go 
without some serious hardware hacking.

And another "Me too!" . . . my (main) Duo 2300 has a 250 screen, and even 
with a 20GB HD and maxed ram a good T3 battery can last well over 2 hours 
using the backlight, over 3 with no backlight use and all other power 
saving measures. And try reading _any_ color LCD in direct sunlight! 
Sunshine only improves the readability of the active gray LCD. Sadly, it 
took quite awhile and innumerable Duos 250/280 to find a screen without 
the dreaded corner-and-edge-darkening syndrome.

The 400 pixel high screen isn't an issue (for me anyway) with texty tasks 
such as WP, email or even 'wannabe'-browser web surfing. My only major 
complaint with my 2300gs ;-] . . . the complete lack of any prospects for 
wifi. With such a supremely compact and portable 'Book, with its outdoor 
ability where no color-LCD-equipped 'Book can effectively be used, 
network access away from wires would really result in near perfection.
