@A/C 12:12 - you're so bwave!
Okay troll, I'll bite.
The original N7 out specced the original iPad (which appeared after it).
Shall we compare the 2013 models?
iPad 7.9-inch retina display 2048x1536 324ppi.
Nexus 7 7-inch IPS LCD display 1920x1200 323ppi
Did you have a point to make? Because I can't see it here. The long side is almost identical, and the short side is only smaller on the Nexus because it's 16:9 instead of 4:3... A size which means it slips into the back pocket of my jeans, or the inside pocket of my jacket.
Want GPS so you can tether your tablet and use if as a large satnav or use other location based services?
Nexus 7, no problem, GPS is a standard feature across the range.
iPad, no. You need the 3G enabled model (£££$$$)
I would guess you've never even touched a 2013 Nexus 7, it's beautifully made, and doesn't want to slide out of your hand like the iPad (for those times when it's not comfortably tucked into your jacket pocket).
As to why people continue to buy iPads? Easy... It's either:
1) Investment in iOS apps
2) Lack of knowledge of the alternatives
I'll stick with my 2013 N7 (costing £10 less than the 16gig fruity alternative) thank you very much.
