Maybe this is just my consumer perspective but I feel like TomTom really missed on a pivot to other GPS-related products that Garmin has successfully nailed. 10-15 years ago both companies were known mainly for car sat-nav systems but Garmin now has an incredibly diverse product line with well-liked fitness watches, bike computers, exploring/off-grid satellite communicators, marine charts, aviation, etc. Whereas TomTom seems stuck still selling the same handful of automobile satnav products which are surely squeezed to a tiny consume base between smartphone apps and feature-rich car screens.
I know there is map IP as well and maybe that's their only real business opportunity going forward.
The (now discontinued) iMac Pro officially supports 256 GB of RAM. 3rd party RAM resellers claim it will work with 512 GB. I assume any M1 or M2 replacement would support at least the same amount.
