Got one and enjoy. May not have the battery life of a tablet or ereader but you have full Windows applications. Remove the keyboard and it is pretty light.
Get one with 64G. Windows and pre-installed programs take up space on the 32G version. Then get a 64G microSD card and you are set pretty well. oh and a stylus.
There might even be one with a hard drive in the keyboard but I think that would be too tempting and you'd wind up with stuff on the hard drive you want so impractical to leave keyboard behind.
I suggest the Open Source Software route. I use PortableApps.com
http://portableapps.com/ with programs like LibreOffice, Firefox, Thunderbird, VLC. They can be put on the PC's drive or on the microSD. They have a big selection of programs and keep them updated:

You can even have Sigil
http://portableapps.com/apps/office/sigil-portable and calibre
http://portableapps.com/node/20518 (not official PAc release yet).
To read books I use the Firefox Epubreader or the calibre viewer. May not be what people like in a dedicated reader but it can do more.
