Full size foldable portable keybord?

This article is a review of one of the many foldable full size keyboards 
for hand held computers or PDAs (Personal Digital Assistants). It is the 
Stowaway™ keyboard designed for Handspring's Visor line of PDAs. It, 
as its name suggest, is foldable, weighs 7.9 ounces, made of glass-filled 
polycarbonate and aluminum, is, when unfolded, the same size as a 
laptop keyboard and when folded, no bigger then the PDA itself. The 
article discusses the problems of fast PDA input and how incredibly 
hard it is to type on the screen keyboard or learn to write out the little 
characters. As it happens, I own a Visor Deluxe, which I don't use as 
much as I should. I can attest to the fact that the thing is not easy to write 
on and for the last few months, I have been contemplating buying this 
keyboard to use with my Visor to write papers on. Its size, design, and 
portability, make it the perfect solution to one of my concentration problems, 
one that I am fact experiencing now, which is my mind does not like to see 
what it always sees. With this keyboard and my visor I could go and write 
papers for class in places that stimulated my mind and concentrate on 
what I am writing.  The only thing that is stopping me is the price, which is 
about five hundred percent more expensive then a regular key board 
or $99.95.
