Re: black friday/ cyber monday deals for the PI

Since those terms relate to the US date for Thanskgiving (4th Thursday on November). The Pi4B has only be available since late June, those sales have never had Pi4Bs at all. In general, the profit margins on Pis are small enough that the only times they go on sale are either as loss leaders, or if s...

However, ff there isn't room to expose PCIE over the SODIMM200 connector then the only *real* gains would be CPU and USB3 OTG - which then begs the question, does that alone warrant a new CM?
The OTG port on the Pi4B is the "legacy" USB 2.0 port.

Re: Raspberry pi 4 operating systems

I doubt there is a "lighter version". (And, FYI, what is in Raspbian is the LibreOffice fork.) If you need a lighter weight spreadsheet or other such application, look around to see what's available. Alternatively, use a more powerful Pi. In the mean time, if I want to write and I don't want everyth...

Re: Raspberry Pi ** Sold over 25million units **

My impression is that many Pi owners own more than one. Is it possible even though fewer were sold that there were a larger number of separate households that had C64 machines? One might also note that many Pi computers are being used in industrial settings. Hard to say... Certainly among active po...

I agree if the mouse was shorter it would be more comfortable to use. Also if the mouse wheel was heavy and spun with inertia, that would make it seem more premium.

Just wish the lid of the 4B case included a built in large heatsink. The case is injection molded plastic. It would make a really lousy heatsink.

Re: Is it OK to use a 6 port usb desktop charger to power multiple pis?

In addition to what was said above... The device needs to be able to supply 5v at the desired current (3A for a Pi4B, 2.5A for a Pi3B/B+, etc.) at the same time. Don't just go by the single port maximum. Check the power rating for the whole unit. To power 6 Pi4Bs you want it to deliver 18A at 5v.
