It had a cute design, but many perf issues due to the SoCs of the day. An address book with 1000 entries took seconds to open and draw. This was because every line drawn required multiple RPC to the address provider process. On those SoCs there was no TLB or cache PIDs, so you had to flush all of it on context switch. Now imagine an RPC: at least two flushes - one on the way there, one on the way back. On a more modern core it would work a lot better! OUCHY!
