In what way that the 28C and 28S didn't?

Sure the 48SX has a better display and a more standard keyboard, but I can't think of anything it did that was truely novel.


I managed to get a friend who was doing a PhD in the USA at the time to bring mine back when he visited. The cost here was well over twice the price over there. Sadly, the screen lost a column and I've not used it since.

My 28S cost well over $500 here a few years before
