Bought an original iPad Mini this Monday, it is actually significantly cheaper now discounted for 50 and even more if you count in time before new Mini 3 was relased. It comes at 260 at local book store that sells apple gear.
For our standard, mid-european, it is actually affordable and at our household it replaces iPod touch 4 gen, iPhone 4 and one old SD camera. So for us it is very usable, airplaying video to Apple TV 3, playing light/kids games, web and pdf reading, photo stream browsing, light photo and video recording...
Since it replacese an 5 years old iPod touch it is more than an upgrade.
iOS 8 runs OK, it stutter sometimes but we have "everything turnd on" but siri. So all the effects like paralax are on. And it runs well, battery is ok, 3-4 days of usage. It is not as perfect as high powered iPhone 6 or new Air but it is light, thin and has seen more usage than all three devices it replaced (even in short time we had it)
