My Toshiba Miniclick failed so I started to look for a replacement, there was still no alternative to some Chinese versions, cheap or otherwise. The minimum specs I was looking for are ~1Kg weight, CPU (quad), 8Gb RAM, 64GB SSD, removable keyboard. The closest I found, and ordered is similar to the Miniclick, but with a 10" screen rather than 8.9". But this wasn't available for 6 weeks so the search continued.

The Raspberry Pi

The latest version is the Pk4B, with 2,4 or 8Gb of RAM. The full specs are here . . . and whoopie! it's made in the UK.

Other requirements

1. A power supply; It requires a 5v input with 3A available, to power add-ons via USBs and the GPIO pins etc. I bought the recommended 230v to 5v adapter, made in Cambodia
2. An SSD to hold all programme, (Operating system, applications and data): Here I
3. bought a 64Gb SSD pre-installed with RaspPi OS

Keyboard and mouse (Both from CPC Farnel) The mouse is sadly from China but the keyboard from Solvakia

Extras

1. An inline switch for the power supply as the motherboard is live and boots the OS once power is supplied via the UBSC
2. A case to protect it from carelessness and dust.
3. A heat sink and fan to cool the main chip
