There are still some missing applets that I'd love to see ported, such as my beloved PulseAudio Mixer Applet. This applet is a true time saver for me as it allows me to easily select the audio devices I want activated with minimal effort. It comes in very handy when you're running both PC speakers and USB headphones.
One area I give Ubuntu props for are the advances made in regard to privacy controls. With so many other aspects of our computing lives losing privacy each day, it's nice to see that Ubuntu has taken the stance of empowerment in this space.
The privacy controls handle such niceties as history deletion, disabling of file activity, and prevention of application logging.
While the need for these privacy features might seem paranoid, I imagine there are some circumstances with shared computers that might make this an attractive feature to utilize. It's a fantastic crossover between going full-on Kiosk mode and retaining regular desktop PC functionality.
ClickPad support has finally arrived
Finally, Ubuntu has proper support for most ClickPads like the one on the Apple MacBook, among others with this type of trackpad.
Previously, Ubuntu users were forced to use various work-a-rounds, which offered limited functionality for ClickPad enabled notebooks. While the support provided isn't perfect, it's a strong step in the right direction.
Unfortunately, it's reported by Ubuntu's own feature list that ClickPad functionality can be a little buggy with click actions. To put it bluntly, you will not find click action support combined with your ClickPad. It's simply not happening with the Ubuntu 12.04 release.
The good and the bad
After weighing out the good with the bad, I think that I will continue to push myself into using Unity a little bit more. Nothing listed above would be problematic enough to prevent me from using it, as the Unity desktop is now faster and more responsive than in the past.
This isn't to say that I'm going to give up on other desktop environments, rather that I'm willing to spend more time adapting to what Unity has to offer.
As Ubuntu 12.04 comes to fruition, I fully expect that there will be minor issues initially. Then again, I also expect a lot more from the development team and hope that they are keeping a watchful eye as to how they might make future releases of Ubuntu even more compelling than the last.
In the future, some features that I think will ensure an even greater experience would include the prompt to consider creating a dedicated /home/ partition, and the ability to scan my existing system and attempt to match up my components with any open bugs. Those two items are on the top of my wish list.
Nothing to stop me from trying 12.04 myself, but certainly something I'd be excited to try in future releases of Ubuntu down the road.
