The CanaKit Raspberry Pi 4 Complete Starter Kit arrived yesterday evening. I got it up and running before turning in and did more extensive testing today. My overall early impression is “Wow!” Pi4 has all the earmarks of a desktop disruptor. Its tiny size and outrageousy low price is a dramatic departure from clunky and expensive desktops. I’ve always wondered why desktop computers have changed so little in the last ten to twenty years. Laptops, notebooks, tablets, and other computing devices are shrinking in size and price every year or so, but desktops seem to remain the same.

It was only a matter of time before a breakthrough like the Pi4 would occur. Earlier Pi versions didn’t have enough power to replace desktops. The Pi4 is a tipping point, marking the beginning of an era that might eventually see the decline of today’s major desktop producers as well as Microsoft’s monopoly on operating systems. For approximately $150, I have a desktop that can do almost everything my $1500 desktop can do¹.

For example, I’m writing and publishing this article with the Pi4. The interface after booting up is similar to any Windows computer. The browser, Chromium, is nearly identical to Chrome. Both are from Google. Once in browser mode, the differences between Pi4 and standard desktops disappear. LibreOffice suite², included in the operating system, is uncannily similar to MS Office. I’m amazed at how quickly and naturally I’m adapting to Pi4.

For those with lighter needs or looking for a second desktop for limited or mobile tasks, the Pi4 might suffice. For power users, the Pi4 isn’t quite ready for prime time. But it’s an intriguing glimpse into the future of desktop computing. Its diminutive size is its greatest appeal, and its mind-boggling low price is the clincher. The fact that it’s very user friendly adds to its appeal. A quality that’s rarely mentioned in reviews of computers is enjoyment. Truth is, the Pi4 is flat out fun to use. It’s also designed for ease of use. The operating system setup is automated, leading users through a few simple steps. After it’s done, users are also connected to their home Wi-Fi system and ready to go online.

True to the disruptive process, the early adopters aren’t from the usual desktop customer population. They are mostly computer professionals or enthusiasts. But as the Pi advances, it becomes more like a traditional desktop, and, after a certain point, when it can do nearly everything desktops can, the customer base will gradually grow, with longtime desktop users attracted by the huge value differential.

I was skeptical about the Pi4 operating system, Raspbian. Would it be a steep learning curve? What about basic functions and apps such as file management, browsers, word processors, spreadsheets? Would the Pi4 equivalents be good enough? What about power? Can this tiny toy-like machine operate just as quickly as desktops? Thus far, after a day of testing, I’m optimistic that this is a prototype of future desktops. It’ll take a few more iterations in the next five to ten years to fully replace desktops, but I believe it will happen.

The learning curve isn’t very steep at all — except for a few spikes that I’ve covered in the list below. The basic apps are, from what I’ve seen thus far, clones of Windows desktops. Power and speed doesn’t seem to be lacking for the tasks I’ve tried. In Youtube, some 1080p videos experienced hiccups, but most ran smoothy, including other 1080p videos. Graphic quality seems to be a shade below what’s expected in desktop workhorses.

Gaps in the Pi4 instructions or quirks that I’ve discovered thus far:

1. Gareth Halfacree’s The Official Raspberry Pi Beginner’s Guide: How to Use Your New Computer (“Fully updated for Raspberry Pi 4”) can be found, in PDF, here. It’s free for viewing or downloading. The instructions included with the CanaKit and on Raspberry sites that I searched are minimal and don’t link to this comprehensive guide.

2. The Micro SD card is inserted with the front (label side) facing down, away from the board.

3. Like the iPhone Lightning USB power cable, the Pi4 power cable can be inserted into the USB-C charging port without concern for up or down.

4. If you insert a device, such as a thumb drive, into a USB port, you need to eject it correctly. The manual says to click the eject button (icon) on the top right of the screen. The only problem is, there is no eject button. You’ll need to add it via the command line. (Funky leftover from the early days of computing. Surprisingly, Windows has something similar for some systems functions.) Click the Raspberry icon on the top left. In the drop-down menu, click RUN. Next, at the prompt, type “sudo unmount/mnt” without the quotes (source). Once installed, the eject icon will appear only when an ejectable device is inserted in a USB port.

5. If you’re not getting any audio (sound), right click the SPEAKER icon on the top right of the screen. In the drop-down menu, click the unchecked option. (There are only two options.) For example, I’m using headphones for audio. To get sound, I clicked ANALOG, and it worked. It had been set, by default, to the other option, HDMI.

6. The keyboard and mouse seem to be compatible with standard Windows PCs.

7. In FILE MANAGER, to open a folder or document, double-click quickly. If you’re too slow, a renaming window will pop up. If you’re having problems, an alternative is to right click the folder or file name and select OPEN in the drop-down menu.

8. If you’re running two monitors and the right-left position needs to be switched, simply shut down and switch the HDMI ports on the Raspberry.

9. My standard-size SD card reader isn’t recognized by Raspbian.

10. Raspbian, the Debian operating system for the Raspberry Pi 4, is on the SD card. To switch to a different OS, simply insert and set it up on a different card.

11. The mouse can be connected to one of the USB ports on the keyboard.

12. My external CD/DVD drive isn’t recognized by Raspbian. The drive has two USB connectors but no power supply of its own.

13. External hard-disk drives with power supplies are supposed to work with Raspbian. In my case, the drive was recognized, but the files weren’t. I guess the drive will have to be formatted via Raspbian. [Update 8/3/19] After a Window’s scan and repair, my WD 1TB external hard drive (with its own power supply) now works with Pi4. This means that Pi4 is compatible with hard drives that work in Windows systems. This will allow file sharing with Windows computers.

In closing, I must acknowledge and thank the UK-based Raspberry Pi Foundation, a nonprofit charity devoted to universal access to the power of computing and digital devices, for this amazing gift to the world.
