decided he wants an iPad mini
is this not an ipod touch?
I assume that Apple have re-defined the "inch"? Apparently, seven of the standard inches are too small for an iPad.
And as Apple have never admitted to the existence of a smaller iPad, any sizes quoted have been purely media speculation. As many smaller pads have a 7" screen, analysts and bloggers have been saying the 'iPad Mini' will be 7", while others who are a bit more savvy have said it'll be 7.85", which makes more sense, as that's close to the size of a paperback book page.
This smaller Pad makes more sense for youngsters, and it'll be a great thing to use with OS maps, using Viewranger or UK Map. I can see it being incorporated into car entertainment and navigation systems too, a dash mount with CoPilot or TomTom installed would be really nifty.
