Brad, I see how Tiles may be useful for the way you work. But, I find the functionality limited and two dimensional. I use a virtual desktop software from another company with Windowblinds, ObjectDock, and Fences to define a multi-faceted, multi-dimensional workspace. Each vDesktop has multiple applications, web pages, with some common tools automatically replicated across all vDesktops (Notepad++ for example). Tiles are just too cumbersome and limited; even if it allows embedded tiles.
Having been a customer since 1990-something, I am disappointed at the deprecation of your virtual desktop software. The docks on my ObjectDock have grown substantially; per vDesktop Docks would be very useful. I think you are limiting the way people can use their environment by trying to enhance a 2D model, instead of really implementing a multi-dimensional workspace with multiple 2D desktops embedded with common apps/tools.
Sure, desktop tools do not generate as much gross revenue as games. But, quality workspace tools are very hard to find; and can get a premium price if built correctly.
