The 600 is quite limited as it only has up to 2MB Chip. Think of it as an upgraded 500 with a HD. (You can add an accelerator for faster CPU and more RAM or get a SRAM PCMCIA card for 4MB Fast but those are very rare and expensive!) So it will be limited to mostly games and some older apps, but nothing more modern like networking and web browsing, etc... Even WHDLoad is tough as there a quite a few games that need a Fast RAM, an 020 or AGA...
You can use it for games, just get a PCMCIA Compact Flash card for it and load it up with a bunch of WHDLoad games and just keep the ones that run on a stock 600 on there and ditch the rest...
