The Linux Mint Blog just announced the release of Linux Mint 10 main edition, codenamed Julia, RC1. Based upon, and compatible with Ubuntu 10:10, Linux Mint continues to lead the desktop linux experience.
Keep in mind that this is pre-release software and may contain bugs. Still, my previous experience with Mint gave me the confidence to install it on my laptop. I opted to do a clean install due to past problems with upgrade installs.
This RC seems pretty stable and I would imagine that a final release will be ready within a week or two.
As Linux continues to improve the reasons to put up with the lock-in, lock-down, lock-up mentality of Windows or OS X continue to whither.
