What do you like best?
RAM Usage is less than 1/2 of that of UBuntu on a typical installation and less than 1/3rd when working off a Live CD . It is a lighter flavor of linux / Ubuntu and strongly recommended for users who wish to use Unix, without paying for huge Window's licensing fees and have a low capacity hardware. It takes up much less disk space and memory than otherwise.
What do you dislike?
Not many applications support LUbuntu as much as they do UBuntu. Application community needs to adopt LUbuntu and develop apps compatible with LUBuntu. Though most UBuntu apps work on LUBuntu, they are not optimized for LUbuntu
Recommendations to others considering the product
Very light weight and highly recommended for users who wish to transition from Windows to Linux, but find Ubuntu and Mac very steep. Highly recommended for its very low memory usage, high speed (as a result) and excellent performance on basic hardware.
What business problems are you solving with the product? What benefits have you realized?
I used it for personal purposes to edit, write and send documents as well as do some programming. I use a Macbook, a Unix workstation and LUBuntu to stress test some applications developed in our organization. I find LUbuntu to be a very easy to use light weight OS, allowing greater manipulation of the kernel and its functionalities.
