iPhone 4. As exciting as the launch of the iPhone 4 was, it was accompanied by some uncharacteristic engineering flaws--at least for Apple, and some horrendous customer support. The infamous "antenna-gate" problem led Apple to implement a program to issue cases for iPhone 4 users, and users also experienced a variety of other issues including problems with the proximity sensor that could lead to embarrassing situations mid-call. As 2010 winds down, it seems the bugs have been more or less worked out, but Steve Jobs and Apple spoke with a hint of disdain for users when addressing the issue, and seemed to only reluctantly deal with the matter to shut up disgruntled users.

White iPhone 4. Where is it? I am not sure why there needs to be a black and a white iPhone 4, but Apple led everyone to believe that a white iPhone4 would be available. since the launch of the iPhone 4, but as of right now there is still no such device available--at least to the general public.

Adobe Flash. I have gone back and forth personally on this issue. On the one hand, as an iPhone and iPad user, I don't often encounter scenarios where the lack of Adobe Flash support is an issue. Most of the Flash-based content on the Web is ads that I don't want to see anyway. However, I keep coming back to the basic concept of user choice. It might affect performance and battery life and lead to an abysmal smartphone or tablet experience, but Apple can still make Adobe Flash an option and leave that decision to me.

Death of XServer. Outside of the Apple loyalist fanbase, the OS X-based , but for those who rely on it, it still fills a need. On the upside, Apple is offering alternative hardware platforms capable of filling the OS X server role, but they are not rack mountable as the XServer was--making them much less data center friendly.
