We had a Internet Wholesaler in our previous residence who wanted to do the retail side as well. They had the monopoly on the estate we were in, so the ACCC forced them to break up.
With multiple retailers, we suddenly had much better customer assistance, but prices stayed the same.
Because the hardware is being made obsolete for a reason. They are inefficient compared to modern hardware, consume way too much power and there are cheaper and more powerful options available.
A modern ARM-based computer like the Raspberry Pi 5 can outperform most computers and laptops running Windows 10 and have a smaller environmental footprint.
The problem is that the obsolete hardware is not cost effective to decommission and recycle. They have not been designed for an environmentally conscious world.
