Depending upon your use, 3 GB is a huge amount of memory. I have a Raspberry Pi with 512 MB of RAM, and rarely run out of physical memory (the CPU is a different story though). That is running a GUI at 1920x1080, FireFox, Thunderbird, LibreOffice, and assorted other applications. Of course Windows is heavier than that, as are most Linux desktop environments, but it does go to show that you can do a lot with very little.
That being said, the memory limit in 32-bit Windows is quite artificial and I don't understand why Microsoft carried it over to Windows 7. PAE allows the OS to address a much larger address space. Support is built into various versions of Windows (as well as Linux).
