I use my headphones all the time on multiple devices: cell phone, tablet, laptop, desktop, wife's phone, wife's tablet, friends' devices. No extra batteries to charge, just plug the headphones into any device with a Jack and it just works. This trend of removing ubiquitous jacks is so annoying. I will not buy any new device that doesn't have a headphone jack. If it comes with wireless headphone capability, great! But it better also have a wired headphone jack, or my money is going toward something else!

If it's not an April Fools joke, it's one of the dumbest ideas I've ever seen on Slashdot!

The developers were very clear that 4.0 was meant to be a dirty release in order to get the development ball rolling on applications. I have been following the dev closely and for each new milestone, I have tried the live cds. I wouldnt dare use it as my main desktop yet. If you thought 4.0 was supposed to be stable, you obviously dont read or pay attention to what the devs have been saying all along! I really liked the new direction the 4.x is headed in. It will take some getting used to for those who naturally fear change, but by 4.2 or later, I am sure we will look back and praise the devs brave steps... or curse them, ha! We will have to wait and see how Kde shapes. I think the growing pains will be worth it.
