Very much so, I had a Sam Coupe and it was a lovely machine but it came our about a year or two too late and had some firmware bugs. If it had come out in 88 or 87 it might have gained some serious traction and had spectrum users switch to it.
The Telestrat seems to fit more in the second wave of the original 8 bit era - with the Spectrum +2, the C=128, and so on. The SAM and the C65 which this piece talks about were later (late eighties, not mid eighties) and seem to have been much more capable machines: the SAM, for example, had 256K of RAM, expandable to 4.5M, 6 channel stereo sound, and a 6MHz processor (compare to the Atari ST or Amiga 500's 68K running at 7.1-8MHz - vs. the Spectrum's Z80 at 3.5MHz and the C=64's 6502 at 1MHz). This was really about trying to create 8-bit machines which could survive in the 16-bit era, easing the transition for users and developers.
Just mention that comparing MHz is not quite right in that era. For example Speccy's 3.5MHz were not that much of an advantage compared with the 1MHz of the C64 if you take into account that it didn't have hardware sprites and all had to be implemented by software, 48K models didn't have dedicated audio chip, etc.
The lack of hardware sprites was easily overcome by the raw speed of the spectrums CPU. Also at anything other than sprite focused games, ie vector graphics or the like the Spectrum smoked the C64. And even with sprites the C64 hardware was limited to 8 before you had to do strange multiplexing.
Sound wise the C64 was better but in terms of speed the Spectrum dominated.
I didn't say what was best, I said that comparing "only" MHz is missing part of the picture. Today machines are easier to compare because they have similar functionality, but back in the day it was different.
I had a ZX Spectrum +2A back in the day and I've programmed several games for the speccy, and the attribute clash was a pain :)
True, thats the right context - in my case though, the Telestrat was "the machine that almost made it to the 90's" in a similar fashion.
It was a great time to be interested in computers. Much complexity, many options, and so little time .. which eventually ran out for all of it. Only a handful of us are still using these machines for things these days..
