I really dislike this generalization. There are often times, many legitimate engineering reasons things change. It's up to the company to ease the transition whenever it does. Most companies just really don't care, because people buy stuff regardless.
Random rumors like the iPhone port where they get exaggerated until people are just flipping out and generalizing "omg im not buying anymore apple stuff blah blah blah blah" when not only has it not yet been done, but they don't know what else is changing. Ivybridge is another perfect example, there are a lot of people that just run around saying "since ivybridge was a flop...." when its the best CPU Intel has put out yet!
Judge a product when it's released, not on extremely questionable rumors.
And TBH, I don't think apple will flat out drop the dock without a good plan; There are a LOT of cars and various other things available, and they know this. They have a certification program! Not to mention the recent Siri integration. Apple has an excellent track record of listening to its users wants/needs.
never said i wasn't buying any more apple products i just no longer buy there (or third party) accessory's unless there is no choice.
i have two i-homes ($100 wasted each) numerous chargers for cars and home and tones of cases/skins that were all basically useless a few months after i got them because of my decision to upgrade.
im just alot more hesitant to buy anything apple related these days as there prices are high and product longevity is short.
even still ill be getting a new iphone here in a few months but probably wont bother with many ad-ons for it unless i cant live without them.
