I upgraded my laptop, stybba, from Ubuntu 9.10 (Karmic Koala) to 10.04 (Lucid Lynx) Tuesday evening. Some first impressions:
Look-and-feel The purple default background and theme is nice. No complaints on that.
Sound Audacity works with no modifications or adjustments...podcasting continues with less stress.
RhythmBox The combination of OS upgrade and RhythmBox upgrade now recognizes my iPod Touch 3G without jumping through any extra hoops. KK saw the Touch as a storage device, but not as a MP3 player. Now, I plug up the Touch, RhythmBox pops up, and it syncs. The only issue I've encountered so far is that video podcasts from MSNBC (gotta have my Olbermann and Maddow) come in as video files, but RhythmBox syncs them as audio-only files to the device.
OpenOffice.org The 3.2 version has Oracle's logo now. Suppose that was inevitable.
Otherwise, everything is running the way it did prior to the upgrade, and that's a solid endorsement. Will see what else develops in the next few days.
