Not really. I once used OS/2 Warp on an old Pentium. Here is some background. aBasically, Os/2 is supperior in terms of areas no longer seen as important, and was once superior to linux, but Linux has caught up with it, and is superior in a number of ways.
I would still use it, if it wasn’t for hardware incompatibility. In fact, while Linux is far superior to Windows, Os/2 is/was superior to both. At least, back in it’s heyday. For example, it has far better compatibility with Windows 95, a superior gui, and is pretty much the default choice for ATMs. However, Linux is quickly gaining ground on Windows compatibility, and Linux works with a much further range of hardware, and the Gui is more adaptable in some, but not all ways. The thing is, however, since Linux is Open Source, while Os/2 is not, anyone (smart and dedicated enough) can decide to reverse engineer OS/2’s advantages, and integrate them into Linux. The same can tot be said for OS/2.
In fact, as I recall, the process has already started.
