There are other companies that release devices on a 6 month cycle. Or do what Samsung does. Releases the S3 as their flagship phone. 6 months later releases the Note 2 as their flagship phone..but its not the S4 so it doesnt really count to people somehow.
I think the main reason the 4 was released so fast was to make the product line completely lightning cable friendly. And obvousily they were going to upgrade other things as well to make it not just be a new one with a different adapter. While I can see new iPads in March. I believe it will be to get back on the same upgrade schedule. And theyll go back to yearly updates.
No it's not the S4 so obviously it doesn't count, it's a physically different device and model (think iPad and iPad Mini).
Here's the problem with Apple releasing so many iPads (not talking about the Mini) in so little time. Bob buys the new iPad at $500. Six months later the next one comes out. Does his device physically get worse? Not at all. However, the
value of his "new" iPad drops by at least $100
instantly. This is expected to happen at least one
year later, not in half that time. If someone's rich and/or
never ever sells any of their devices I can see why they wouldn't care, but for a lot of people that's how they keep pace with technology.
And the Android comparison was just weak (from another poster). At least keep it to one manufacturer. Take Motorola, they kept releasing model after model in quick succession and it certainly didn't help with customer loyalty.
