Ok guys here goes hopefully someone here will be able to save me spending loads of cash i do not require to in my quest for a mobile PC.
What i am essentially seeking is a mobile way of writing in word, e-reading, possibly emails, pictures,vids,address book thats about it on as large a ascreen as is possible due to failing eyesight for as little money as possible, so as to be able to
1- Work in word, thus able to transfer straight to my main computer  [so i can when i get a ureka moment  write my thoughts, ideas, and pages, as i often do late at night  [i author a few Volkswagen websites and constantly write pages in the middle of the night].
2- Be able to take decent quality images for later use on my sites.
3- Be able to upload, store and use E-reader e-books.
4- Have or be able to have its memory upgraded easily/cheaply
5 -Have as large a COLOUR screen as possible [eyesight not that great]
6- Possibly be able to send e-mails/connect to net but not that important

Most of all it has to be essentially a minature pc have big colour screen and be able to use and store images, word docs and be reasonably priced doesn't need to be a brand new model, not fussed about make, model, colour size shape etc sop long as price is good, memory can be upgraded etc...

Your help would be appriciated as my other half is going crazy at me lying in bed of a night with a laptop in her face essentially keeping her awake...

Please therefore suggets makes, models, sources and suggestions at will to enable me to make an informed decision...

Also sources of Free software, e-books, or applications in advance of purchasing would be helpful
