I am on little sleep, so rambling a bit.
Does anyone else think Apple designs products intentionally as 2-3 versions out from the start?
Lets take the iPad. Price it at 499$ for 16GB WiFi. but lets leave it at 256mb RAM, and leave out front\rear cameras like we have on other iPhone\iPod devices.
We also can sell an adapter to accept a SD card reader, then integrate this feature into the next version based on sales of the adapter.
They could have easily added the extra RAM and cameras in the first generation, but would leave less to look forward\want in the 2nd generation.
More profit with less features & functions now, and we can add these in for the same price point later, as manufacturing costs go down from making millions of iPhones and iPods.
