This article is super-confusing. You have been able to buy 4G Pi4's for a while. What the article is reporting is actually a price decrease in the smaller capacity 2G variant.
Not especially, no. The core product is the $35 computer, and has been since Raspberry Pi began. That product, the $35 Raspberry Pi, now has 2GB of RAM. Yes, other configurations are available, including the previous core product if there's a reason why you'd want the 1GB version.
The article seems to suggest that the 4gb model has been outselling the $35 one.
That doesn't change anything. The RPi is all about the price point. Yes, you can get other configurations, but the whole point of the Foundation is that $35 (or cheaper) machine - an affordable computer, built to a specific price point, with the aim of putting a "tinkering" computer into the hands of as many kids (and interested adults) as possible. It's nice that people are buying the things for various more mundane purposes, as that sort of subsidizes the main purpose... but the main purpose is still to provide an educational machine at an affordable price, and the $35 price point is a big part of that.
Yes, it is. We deal with Raspberry Pis every day at work (for... reasons) and even I had to re-read a couple times to understand what they were talking about. It would've been easier for them to say 'for the same price you paid the original RPi, now you can get an RPi 4 with double the memory the original had and much, much faster processor'.
Thanks for pointing this out. I literally bought a Pi4 yesterday to set up a Pi-Hole on, and I was choked when I read this headline!
