About the same time PC-compatibles were getting more powerful and cheaper, so I moved on. The HP handheld community of the '70s and '80s has split into several camps. Now, HP has released the 49G , the machine they really should have built in 1990. Most HP users moved to PC-compatibles. Others found clever, proprietary platforms like Amiga, Forth and Linux .
Evolution is ruthless.
Everything is a compromise. By the way, in 1981 I finally got an HP-41CV . And it worked reliably until January of 2000. Back to Palmtops . . . I realized, finally, that little handhelds in sealed boxes, no matter who makes them, offer no upgrade path.
