Tim here, responding in-line: > How much storage do I need? That's a bit like asking how long a piece of string you need. It depends on what you're doing with it. The base Raspbian operating system should fit in a couple gigabytes (I think it fits on a 2GB card last time I checked), however that doesn't leave much room for *your* files. If you use some other Raspberry Pi distribution, you'd want to take into consideration its base image-size. That said, an 8GB card should be plenty big-enough, and I see 64GB SD cards for under $10. However, note that the *speed* is likely more important than the space since SD cards can be a bit slow. I have some older 4GB cards that are slower than class-10 and they are *painful* to run from. Also, buy a reputable brand from a reputable vendor. There are a LOT of rubbish cards out there that report large sizes but only have some minimal capacity and you don't find that out until seve3ral months down the road. > And how many usb-ports are there on the 400? There are two USB 3.0 ports and one USB 2.0 (all USB-A form-factor) And there's also a USB-C port for power-supply. > Does it support Bluetooth and Wifi? Yes, it has Bluetoogh 5.0 with BLE, and Wifi You can read the full specs here https://www.raspberrypi.com/products/raspberry-pi-400/specifications/ I don't know what your accessibility-preferences are, but it might be important to note that it doesn't have an audio-out jack (standard 3mm headphone jack). So you intend to use TTS rather than Braille or a screen-magnifier, you would either need to get an HDMI-to-headphone adapter or a USB audio device (I picked one up recently for under $10). Additionally, I wrote up a detailed description identifying the ports and keyboard layout, and Mike posted it here: http://www.raspberryvi.org/pages/guides/board-description.html#model-400 in case you want the nitty-gritty for familiarizing yourself with the unit.
