Had a chat with my mum today (late 60's) and she wants to replace the laptop with a tablet. She barely uses the lappy as it's too bulky (suffered a few strokes and has issues with typing/moving easily)
So, i agree that a tablet would likely be the best solution for her, lighter, easier to use, no typing per se.
I'm a Nexus person, barely have used an iPod/Pad/etc
The wife is an Ipod/Pad person, barley used an Android machine.
So it's hard for either of us to be truely subjective on it.
It will be used purely for internet browsing and watching vids of my boy etc. Possibly for iPlayer/4OD etc too, but in all honesty, unlikely.
Budget isn't a factor, just ease of use really.
