> The hardware is impeccable, but nobody had any problem with the thickness of the first iPad and that's what they changed.
They changed substantially more than that:
- More RAM, so browsing and multi-tasking is better
- Faster processor, so apps launch faster
- Better graphics processor, so developers can make even prettier games or do crazy graphics transforms in realtime like PhotoBooth
- Cameras for video conferencing
- It's lighter, so it's easier to carry around
None of these things is trivial, but it's an incremental hardware upgrade. That's how Apple's cycles work: Major revisions every two years, incremental bumps in between.
Meanwhile, Apple's OS release schedule isn't coupled to its iPad release schedule. iOS 5 will be announced sometime in the next month, if the past is any indication.
Apple does better than anyone else at continually improving its software and making it available to previously-shipped devices. I doubt the iPad is going to be left in the cold.
