I miss my iBook 1,2 12''.I used my nearly-new-to-me iBook G4 to share an internet connection via Firewire with my 2007 C2D iMac (using my new 50-cent FW800/400 cable!), so I could do a little browsing. The iMac's wifi hasn't worked since upgrading it to unsupported High Sierra with one of dosdude1's patches (an expected and worthwhile trade-off), so it's been a hard-wired beast. Its former bridged ethernet connection from a Windows machine was unavailable while I installed Linux Mint on the PC. Fun times!

Today Im setting an VPN connection on my G4 server for just having a safe torrent downloader with Transmission, loading torrents via the webUI.
@Imixmuan At this point, it should handle all Internet tasks fine. Single Board Computers have made incredible advancements in recent years.
At the very least, they definitely have horsepower to spare.
For the price of a working Rpi4 (board + case + charger + wires) you can have a Core powered Mac Mini, that would be way more reliable.
But yes Rpi are an option for basic internet stuff.
