My main distro is Ubuntu 10.04 LTS, But I have tried Mint, Puppy, Bodhi, Ubuntu 11.10, & several others. I have never heard of Lime & it doesn't appear on the top 100 distros at Distrowatch (if you Google that you can get a lot of info on the latest distros). Be sure you study system requirements - some distros are designed to work with high-end PCs & others are designed especially for old clunkers. Most are somewhere between and work with the kind of equipment most of us have. Ubuntu & Mint are more "user-friendly" than many other varieties and require less tweaking to make them work. Most of the more popular distros have their own user forums where you can get help from other users (& look at the kind of problems people have with that version). Make sure you can find replacements for any Windows software you "must have" before you erase Windows. I dual-booted Ubuntu and Windows XP for about four years before I did away with XP. I am not a gamer or a power-user, so my requirements aren't very strict, but I enjoy many things about Linux - especially the fact that it runs faster than XP (the last Windows version I have used) & doesn't need a lot of virus protection. (You can be hacked on Linux, but it seldom happens to anyone who uses good sense).
