KDE4 has given much to the computing world at the cost of its bloated composition. GNOME is fast & flexible but mostly liked by hardcore conventional Linux users. LXDE is a relatively new and highly adoptable free and open source desktop environment . Although designed to work on the older resource-constrained computers it works very well on new generation computers .
LXDE is fast , uncluttered & easy to work on . As a home user I prefer one package per task distribution installation and LXDE works very efficiently fulfilling my this demand.
LXDE puts less strain on my computer`s physical memory making it much easier for me to perform my daily tasks without my mind being diverted to the response rate of my computer as it happens on KDE4.
The one bad thing about LXDE is the lack of ability to move and place icons on desktop which is really annoying . I like to place and group different icons sets on my desktop according to my needs so I don not need to think and locate icons of different packages at times of need. LXDE leaves icons glued to one place and I feel pissed off with this always.
LXDE panel also has limitations and it takes some time to learn how to adjust to LXDE according to one`s needs.
LXDE also lacks a well defined control center as is offered by KDE and GNOME and this is a real big short coming. Many distributions supply custom made tools for LXDE management because of lack of a native LXDE control center. Openbox is used along with LXDE and it helps to overcome many shortcomings of LXDE.
To become a fully adoptable and popular desktop environment for home computing LXDE development team has to concentrate on these shortcomings . Home users who want to escape the bugs of Windows would not want to fall prey to the complexities of how to set a desktop environment according to their requirements and the decades of windowing will relapse back if Linux stops racing for the "latest & greatest" things and seriously address the pitfalls which are constantly ignored. Home users can never be Linux gurus and the will not bother to learn new computing skills . They need a flexible, safe and easily adoptable working operating systems and desktop environments. LXDE is one such highly suitable desktop environment but needs serious combing out for things which will play a role in its popularity in home users.
