I have two computing devices with keyboards: one is a Raspberry Pi 400 released in 2000 and which I bought in April of 2022; the other is laptop, my MacBook Pro, released in late 2013 and which I purchased in August of 2014.
The specifications are as follows:
MacBook Pro Retina 13" with 2560-by-1600 resolution at 227 pixels per inch and 2.4GHz dual-core Intel Core i5 processor (Turbo Boost up to 2.9GHz) with 3MB shared L3 cache. It has a 256GB SSD and 8GB of 1600MHz DDR3L onboard memory. The Intel Iris Graphics support dual display and video mirroring, simultaneously supports full native resolution on the built-in display and up to 2560 by 1600 pixels on up to two external displays, both at millions of colors. There is a 720p FaceTime HD camera.
The Raspberry Pi 400 contains the same general specifications as the Raspberry Pi 4 but is tweaked for this new form factor. Thanks to work on the device’s thermal performance, the processor on Pi 400 has an increased clock speed over the base Pi 4. As a result, the Pi 400 has an increased clock rate from 1.5 GHz to 1.8 GHz. Meaning you should get slightly better performance when using this device. Unlike the Pi 4, there is only one variant of the Raspberry Pi 400. You can only get 4GB of memory with this device. Another change with this device is that it only has three USB ports. One is a USB 2.0 port, and the other two are USB 3.0 ports. The rest of the specifications of the device remains the same as the Raspberry Pi 4. You have access to the same GPIO pins, gigabit ethernet, Wi-Fi, and Bluetooth as the base device.
The Raspberry Pi 4 performs well enough given that it is a budget device. It could definitely benefit from 8GB of RAM instead of only half that. At times there is a noticeable lag in keyboard response if too many tabs are open in the Chromium browser. The Bluetooth is faulty and I've been unable to connect wireless earphones to the device. This is a problem since for some unknown reason there is no earphone jack. I've created a workaround that I've discussed in an earlier post. The keyboard is far less satisfying than the one of the laptop. The lack of a fully fledged browser like Chrome is annoying but with the Raspberry Pi OS that's what you get. I've tried booting into Linux but things didn't go and again I've described the experience in earlier posts. There's no battery for the Pi, it must be connected to an AC power supply but its form factor makes it very portable. To function, it just needs power and a monitor or TV.
The MacBook Pro model that I have is currently selling for about US$250 on Amazon while the Raspberry Pi 400 Personal Computer Kit is selling for about US$100.
