What is the best handy pc i can use to read pdf files?, i need to get a cheap good one with a large space or a memory cards support or what ever can save my spaces, i need that for portabllity as i travel alot and i can't get my laptop to work on the african roads, there is no electricity or internet so my laptop can't stand on for more than 2 hours then you should try to get a partner to talk to him till you arrive

About any handy can read pdf's. IF you look at the list on the adobe site (http://www.adobe.com/products/acrobat/readstep2.html?c=us) you will see that it has a reader for Palm, PocketPC and Symbian.

So you still have plenty of choices . The problem is, I don't know any bad handy, so it'll be up to you the pick the right one.

Here is an example: http://global.acer.com/products/pda/n30.htm
It has a SD/MMC card slot and a USB host connector, wich means you can connect a USB flash disk or even a USB HDD case!
Price seems ok here in Belgium, it costs about 220 Euro's

If you realy want a long battery life (the n30 works 8hours w/o backlight) you could look for a pda that has a battery pack (my dad's Ipaq has one).

There are some devices that are made specifically just for reading PDF documents and other formats for eBooks. One such device is the Gemstar eBook. Here is a link to a few devices and their prices. You can use this as a starting point to see whats available for reading documents then try looking around for a place that sells them for pretty cheap.
