Binoculars, dont sell yourself short. I make do with an 850 at home. The number of systems (including professionally used) I have seen using 10% of the power is untrue. Worst example was about 7 years ago. Very nice top of the range Tecra laptop. It was never undocked and only used to run a mainframe emulation package. A 386 would have done the job.
Once having moved to PCs from other micros I was using a 4.77 mhz with 256KB ram and Dos 2!. It really was a mistake once we reached the stage of not being able to fit the OS, application and data on the same 360KB floppy disk!
