Overview: 

My old IBM Thinkpad 600E, what a machine.  Not even close to enough power to do things like youtube and such, but as far as FreeDOS and KolibriOS are concerned, its quite well, overpowered. having around 200MB XMS memory in dos is a bit excessive, yes it has a ramdisk for temp files. and as far as kolibriOS, goes, givin that that OS can run on a Pentium I with MMS, and 8MB RAM, This old laptop is naturally quite suited for it.

As far as dos GUIs go, it blazes through the likes of SEAL 2 and the far less developed OZONE, oddly, only one DOS gui i tried had trouble, ill give you a hint it starts with "W" :p

With games, it has the usual selection of Apogee shareware, and also games like Duke Nukem 3D, the DOS version of Transport Tycoon Delux, and a selection of many other games.

And like any avid DOS user there are various other programs too: such as The Links web browser (just about the only graphical DOS browser that still gets updated),  some media players, such as an Allegro+VESA port of MPLAYER, and yes, it can just barely play a 320x240 OGG Theora Voribis Video. pausing slightly when the buffer runs out.

To conclude, its not the most capable computer, but it does work, and still manages to out-preform DOSBOX.
