Yes, about a month ago I switched from a WinXP laptop at work to a Linux Mint 9 main edition (Gnome) 32 bit laptop. I use the laptop to do mostly word processing but I also surf the net a bit, send and receive e-mail, do some spreadsheet work, create PDFs occasionally, etc.
The hardware I am using is a Dell Vostro 1015 (
http://www.dell.com/us/business/p/vostro-1015/pd?oc=bqctlt13&model_id=vostro-1015) which I purchased from Dell specifically for the purpose of putting LM9 on it for use in my office. The hardware/OS compatibility is very good but not perfect... the system speakers are very basic and the speakers do not mute when I plug in my earphones (it's a software issue that I have not sorted out yet). The only other problem (minor) is that I can not get my touchpad to scroll (probably another minor software issue). Otherwise the machine runs great...
Advantages? The most useful advantage is that it is NOT Windows. It does not need Internet security (expensive, annoying, performance crippling) bloat-ware. It comes with everything I need & use every day right out of the box. It runs faster than Windoze on most hardware and it runs pretty well on old &/or modest hardware. It is less memory hungry. It is faster and easier to install than windows.
Disadvantages? Running Windoze software can sometimes be a tedious, clumsy, and/or annoying to set-up. The learning curve initially can be somewhat steep if you will be expected to troubleshoot it. The learning curve for a "regular user" is relatively shallow - mostly involving learning how to use a different word processor, or browser, or e-mail client, etc. - not all that difficult really.
I am not sure what you mean by "management software" so I assume that I am not using any...
