10 operating systems you've never heard of
After a wave of operating system releases, it's easy to become somewhat bored with the software side of computing.
Windows 7 is here and looking like the "real" Vista for many; Mac OS X 10.6, meanwhile, adds spit-shine to Leopard and gives its engine a good tuning too. In the Linux camp, distributions are taking regular steps forward in usability.
But it's all become rather routine; a case of incremental improvement rather than revolution. So where's all the real fun happening? Where are the radical new ideas, the Wild West code commits and the geekery and hackery that really drive innovation?
