What tablets/laptops are there for my grandad?

My grandad, aged 79, who just about knows about where the on button on a laptop is, is looking for a device where he can access emails. He has issues typing on my iPhone, and has reading glasses. What would be good for him?

The nokia 2520 is big and cheap, plus windows platform is using big tiles instead of small icons on android/iphone. Windows are make easier for people who has none computer knowledge.

The cleaning spanish lady from where I work has a lumia and she likes it because its stable and buttons are big

If only to access email and minimal other functions and storage and eyesight and dexterity not what it was, there are a couple of potentials.
For a fixed position use in a home where portability is not a concern, I bought my mother a big screen all-in-one. It is not for gamers or power users, but she loves the high definition large screen and full size keyboard and mouse and minimal space and wires involved in it. You can check brand web sites, Best Buy, Walmart, Amazon.com, and other local retailers like Fry's or Microcenter, or Office stores for deals, but one example is:

not running Windows. They can be bought even cheaper, but this is a low performance but 21.5" IPS touch screen unit.
or

Acer Aspire Celeron 4GB DDR3 500GB HDD Capacity 19.5" All-in-One PC Windows 8

They come in many prices and performance levels.

If portability is key and just wants something bigger, Chromebooks and 10.1" tablets are available fairly inexpensively.

And, if cost and a higher weight are not a giant factor, a Lenovo Yoga

or new design tablets like this one:

There are very cheap 7" tablets now:

The key in looking also is the features needed in internet access types.
Some can use 3G/4G wireless, and some only wi-fi, and some also have ethernet.
Some are linked to wireless phone services.

I think ipad mini is the best tablet for him it is easy in the use and getting emails is very easy and its words are big

That's an Ainol Mini Tablet. It's very cool, with android, slim and you can help his Grandad to interact with the Tablet.
