At the risk of sounding like a stuck record, another interesting device from the same period was the Tandy TRS-80/100, a notebook-sized portable that was similar to the HX-20, except that it had a 40x8 character LCD. It was more a mobile wordprocessor, but it had Microsoft BASIC and several expansion options:

The battery life is quoted there as sixteen hours, which is handy if you're a graphomanic trapped taking an aeroplane flight from the UK to Australia. It had 8k up to 32k memory, RS232 etc.
I remember reading somewhere that the HX-20 could be programmed to play the tape at certain times in order to sequence audio events, thus creating a very primitive early sampler.
