The Vega+ was little more (or a lot less) than running a Spectrum emulator on your phone for the handheld experience. And with a phone the games are easy to acquire or may come with some Speccy apps.
Part of the problem from the start was the Vega+ was not a recreation or modernisation of the Spectrum. It was just a box running Linux and a Spectrum emulator with some buttons (no where near enough to play a lot of the games) and a promise of bundling games.
The Recreated Spectrum was at least more useful, if only a USB keyboard really. It had the full case and keyboard and hooked into a emulator running on any iOS or Android device, and bundled games.
Still not a patch on the real thing or a Spectrum Next which takes it to the next level. Though pushing the graphics to the level they have with the Next is making it feel less like a Spectrum in my opinion. As a progression to what the Spectrum could have been replaced with, ignoring the QL, really it would have been a full 16bit machine. But then the kids had moved onto Amiga/Atari anyway.
