A few months ago, I said that even if the only change was making it lighter, I would buy it. Well, now I have it, upgraded from the iPad 4. Current resale value means I paid $300 to upgrade.
After using it all day, I am leaning toward it not being worth it. All the minor performance problems I noticed before are still here (iOS 7 related, I suppose). I'm sick, so I've been laying in bed, holding the iPad upright for a few hours. Other than the more rounded edges being more comfortable, I am actually surprised that the lighter weight isn't more noticeable.
I do like the slightly smaller size, and the matching Smart Cover. I am concerned that a new iPad with the fingerprint scanner, 2gb ram, and laminated display will debut in a year. I am also assuming that apps won't be optimized for 64bit until then as well.
This literally feels like an iPad 4, but lighter. Same cameras. Same RAM. Same screen. Same battery life. The A7 chip is amazing on paper, and the weight loss is nice in practice, but is it $300 nice? I have 14 days to decide, but as of now, I will assume I am returning this.
