The Web still needs to catch up with some of Symbolics Lisp Machine development environment features though.

However, I like to think about it as carrying a Xerox Workstation or an IBM mainframe on my pocket, as both iOS and Android trace back to them.

Smalltalk, Lisp, Mesa/Cedar, bytecode environments with micro-coded CPUs, or JIT services on kernel with portable executables (IBM/Unisys).
