Did you see this Ubuntu 7.04 (feisty) (p)review. Despite what I think about some the recent strategic moves by Ubuntu I am impressed by what is coming. After reading that review I was just thinking "can it get any better than this?". I mean, it's so polished that there's pretty much no real arguments left for anyone who opposes switching to the GNU/Linux desktop based on "it's hard to use" or "it's hard to install software" or anything like that.
Also, this feature of automatically installing codecs for mp3 support is something I don't oppose even ideologically becase it installs gstreamer plugins. It could do the same for video formats by installing ffmpeg. Both gstreamer and ffmpeg are Free Software. Remember, you don't need proproetary w32codecs for 90% of multimedia anymore! That's increasingly becoming a past.
Heck, after seeing this review I am tempted to give it a try once it is released myself, but I'd also check to see which exactly proprietary components (blobs) have been put in. Something tells me none of it will be needed for me and I'd just be able to remove it.
In fact... it is increasingly becoming true that most people don't need any proprietary software on GNU/Linux. Got an R300 ATI card, you don't need proprietary driver for it. Maybe the only remaining area is wifi support, but I don't know much about that to comment. What else is there?
When I step back a bit and look at where has GNU/Linux come, despite everything; it's just freaking awesome and incredible. Sure, I'll continue rallying against compromising (especially when it's not so essential as some make it out to be), but on my "spare" time so to speak I can just sit back and enjoy the accomplishments made so far!
