Thank you for all these brilliant replies.
In my ignorance @ScarfLadysBag I didn’t realise the Oasis was an available subtype of kindle- I thought it was just an old model! After looking it up I think the warmlight option is really great and I am really tempted. The country I live in doesn't seem to have any Oases (sp?!) and amazon won't ship abroad, but I will ring around and ask. What device would you personally opt for if mostly reading articles in PDF format?
A couple of things that worry me: I noticed on YouTube videos that when you touch the screen of any kindle whether to zoom or turn the page or anything else, it sort of flashes inverse colours (black background and white text) incredibly briefly while it makes the changes. Does this bother anyone, either generally or those with sensitive eyes or perception? Is it very different in actuality compared to kindle on say a phone? It really bothered me looking at the youtube videos but I don't know whether I'll get used to it. Is that what you meant @BobbinThreadbare123
And audiobooks- I have some mp3 meditations, can you listen to your own mp3s on the audiobooks? It says something about Bluetooth-- does this mean you need a device like a phone to send it over Bluetooth in the proximity of your kindle? (probably a silly q but does the phone need Internet or 4g etc?)
I guess the follow on question is, are you limited to Audible?
Do the 3g and 4g options for kindle mean you can insert a Sim card?
The Remarkable tablet looks amazing HotWatBot thank you, and I am seriously considering that too, if anyone has any more feedback on it. Such as, is the size OK to handle and is it naturally warmer in lighting as it seems to be, and battery life etc.
And, is there such a think as a colour e-reader that people like for textbooks etc or are we now in tablet territory? Is an ipad no different from a phone or computer or amazon Fire in terms of reading comfort?
Or any other methods people use for reading papers would be great.
As mentioned I have never so much as seen an e-reader in the flesh so I will try to rectify this, which will no doubt help the prevarication!
@Oxyiz that is exactly how I feel and the thing I am most concerned about!
