"I am trying to configure out a really dumbed down and intuitive PC for my grandmother. She recently had a stroke and while she is under my care I would like to repurpose a laptop for her to surf and email her children.

Out here in the UMPC wilderness, there are those of us actually having fun with our tiny little "computers." I'm happily chuggin' along with my Fujitsu U810 (800 MHz!), upgraded with an ssd, a new wifi card and touch-friendly Windows7.
I am anxiously awaiting the transformation that will occur down at the local coffee shoppe, when the fruitcomputer crowd starts using the new Apple tablet instead coffee table sized things they are currently schlepping (with a light up Apple logo, how cute!).
Of course we have to wait for Apple to invent it, and most importantly figure out a way to charge you for every.single.piece. of content that will be displayed on it.
