I have used 2.0, 2.2 and am currently trying the 2.4 beta and haven't had any problems with any of them. I am running on an old netbook, Acer Aspire One made in 2008. Linux Lite is better than any of the other distros I have tried on here. In my opinion, unless you have new hardware there really shouldn't be any issues.
