On the Web page announcing extended support for Debian 6, you state "Users ... are encouraged to upgrade to Debian 7 (“wheezy”)". Well, I tried Debian 7 on my desktop PCs and laptops. My first and strongest impression was of the menu. It is a dumbed-down Ubuntu / Windows 8 style menu that seems better suited to portable devices than to desktops. The Debian 7 menu is not a quick path to the desired app but a series of hurdles to be overcome in order to find the application. Launching an application on a desktop using this menu is not a pleasure, It's a nuisance that is always in the way. I tried Debian 7 "classic", its menu is a pale shadow of the Debian 6 menu that feels like an afterthought, a feature that Debian would rather not include. I tried Xfce, Linux Mint and a few other things, but found nothing satisfactory. Finally I uninstalled Debian 7 and reinstalled Debian 6.
In spite of flagging sales, there are still zillions of users running PCs and laptops. You will recall their reaction to the slap-in-the-face Windows 8 front end at its release. Could that account for the resistant popularity of Windows 7? Why should you too stop serving these users? I would upgrade to Debian 7 or 8 in the blink of an eye if it offered a full-featured desktop menu.
