1.The mice. 98% of the Mac setups out there are NOT using Apple mice, i think that sends a clear message
2.Mac mini, they wasted both their time and the consumer's time with a completely valueless computer that had great potential. Shoulda just combined the Apple TV with it and create a Media centric computer and be done with it.
3. Uncanny ability to never fully give you what you need in a product. For example, Mac Pro lacking true cutting edge graphics, using the same graphics card for two generations of the MBP, iPhone lacking 3G and non replaceable batteries, no headless towers, ancient cinema displays lacking decent ports and height adjustability etc
4. Hypocrisy. If i remember correctly they trash talked the integrated graphics chipset and now two products live off these. They also said mounting a slot load drive vertically slows burn speeds down dramatically and is stupid, again, the iMacs (G5 onwards) live off these
Maybe im ranting and im sure there's some logical explanation for these but this are the things that make me thing....WTF?
