I have only been using LXLE steady for about a month but so far I am loving it! I have it installed in my main laptop, my "on the go" laptop and on my "test" netbook and it performs well on all of them.
I have LXLE on my older homemade computer and it is on my wife's Dell. However, she opted for the newer Macbook Air so the Dell sadly went away quietly. I also have a disk of the powerpc LXLE that I still plan on installing on my iMac G4 that I saved from certain recycling. I have installed LXLE on a number of older computers that were recycled and given away to elderly people who could not afford a computer. It is a good system.
