I had checked already.Mint is a leecher of Ubuntu resources.personally ,I will Never use it.Ubuntu 64-bit anytime.more respect to mepis than mint which even shares ubuntu repos.
I didn't think Linux Mint is bad. Who care what repo it used.......we need user friendly distributions for Linux growth. All people are not geeks. They expects easy to use, Performace, satablity from their operating system. Linux Mint meet all this. It includes many useful tools (MintAssistant, MintBackup, MintDesktop, MintInstall, MintNanny, MintUpdate). All tools are licesnsed under GPL and source code are available for modifications. In the case of proprietary softwares, all we know that these are essential for daily use (Graphics card drivers, MP3, and Adobe Flash).
According to
Linux Mint FAQ: Linux Mint respects the GPL and it also respects the copyrights and licenses of the proprietary software it distributes. However it uses technologies that have been patented in some parts of the World. Most countries do not recognize the legitimacy of software patents so for most of our users this is not a problem. But if you're unlucky and you live in a country where software patents are legally enforcable, you need a version of Linux Mint which is free of patented technologies, and this is what the Light Edition is about.
Finally an important point about Ubuntu x64 edition written by Keir Thomas "You might notice that a 64‐bit version of Ubuntu is also available for download. In my opinion, there’s no need to use this, even if you have a 64‐bit‐capable CPU in your computer, unless your computer has more than 4GB of RAM. The 64‐bit version of Ubuntu has been known to present a handful of annoying compatibility issues that, while not show‐stoppers, can make life more difficult than it needs to be."
