Just bought an iPad as a Christmas present for my partner. It's their first iPad and it'll be used purely for content consumption, so the 10th Gen iPad should've been a foregone conclusion. However, I ended up getting them an Apple refurbished 4th Generation iPad Air instead.
In the UK the 10th Gen iPad is £499 and the iPad Air refurb was £439. As far as value for money goes, the refurb was a no-brainer. Laminated display, magic keyboard support if necessary, same chip etc. Only thing that's different between the two are colour options and the ultra wide camera (and the poorer accessory compatibility on the 10th Gen).
The 10th Gen iPad makes less sense when you factor in outside buying options like refurbished and sales on older models.
