That seems like a very weak excuse. Here is the timeline of the original releases:
- June 2008 >>> iPhone 3G
- June 2009 >>> iPhone 3GS
- April 2010 >>> iPad 1
You can't seriously claim that a device released in April 2010 is to be treated in the same way as a phone released almost 2 years (!) earlier. 2 years is like 2 centuries in the fledgling mobile devices industry.
