I still use my systems daily. Right now, its just my 68010 A2000 with a 40Mb SCSI hard drive and CDROM and indiECS. I use it to code C, play WHD Load, and just generally have fun learning all about amigaOS 3.1. I have an A4000d, but I have no display for it at the moment.
I do often bemoan the cost of the equipment, and sure a WinUAE setup is pretty freaking awesome in terms of raw speed. BUT - there is a sort of je ne sais quoi about the real deal that I enjoy. I'm going to soup this A2000 up as much as I can, and once the recap is done on the 4000 it will get some love as well.
I like seeing what I can accomplish with what I have.
