Apple announces original ipad in winter, not available until the spring
Apple announces the original iphone in january, not available until the summer.
It seems apple has a history of having a huge delay time between when a product is announced and when it's available for the first version of that software.
And Motorola/Verizon is likely the second best marketing team out there.
Again. DroidDoes campaign
In both of these cases Apple was introducing an entirely new platform. The early announcement of the original iPhone allowed time to build up mainstream hype. Also, give accessory manufacturers time to make... accessories.
As for the iPad, Apple (wisely) announced it well in advance of launch to allow devs time to make apps specifically for the screen size and form factor. This is why there were thousands of iPad-specific apps upon launch.
Google and the rest of the tech industry could learn many things from Apple. Imagine if HP had come out during their webOS event and said the Pre3 and the TouchPad would be available for purchase the next week?
