For the wish list ,
Being able to read Adobie files ( for tech manuels ) would be nice ,
Removable storage would be nice ( LOOOOTS of tech manuels ) ,
Beable to use a spread sheet , ( some times I have to do some calkulations at work ) ,
A color screen would be nice , but NOT nessary ,
web surfing and e- mail , nice but NOT nessary .

Now it WILL have to be and have ,
weather proff , i work out side Mostly , and I don't melt in the rain , neather should it
Drop proff , hell who am I kidding I should be able to throw it accross the room and bounce it off a wall and not bust into a bigillion expencive little bits glass and plastic .
