Robert Szeleney will never cease to amaze us. After developing a software OpenGL stack and porting Quake 1&2 on top, this time around he has a preliminary JavaVM core running simple Java programs for his OS, SkyOS. Indeed, SkyOS has gone where no other hobby OS has ever gone before with these new features (not even AtheOS ever had such goodies).However, there are problems with the OS on other, lower levels. The OS has very few trial users because of its lack of a unique filesystem and its extremely cumbersome way of running the OS (you will need a FAT12/16 partition or burn CDs and ‘dd’ to floppies each time there is a newer version).
Moreover, the OS looks really bad, it has an extremely unpolished look. If Robert could fix these issues before aiming high at Java, GL and other exotic, it would surely bring him a respectable amount of userbase and most importantly, developers.
