Wdym? I have that thing and solaar did a job and work perfectly on my kubuntu

any Thinkpad is fine. My E14 Gen2 is very good with Ubuntu

push notifications and widgets

Verdana, Tahoma and Source code pro is good for eyes

Macros on excel especially with vba are very important and that is why Excel is an industry standard for spreadsheet software. BYW, no alternatives with strong compatibility with that.

it is not easy because there are critical software that people used to work that are not available in Linux such as MS Excel, solidworks, Adobe Suites.

I tried to use Voyager on ios 17 to add widget. But, the option is unavailable. Howver Apollo sideloaded can do that.

there is no push notification and widget like original Apollo

if your work requires CUDA then nvidia is the only option

it is not really dead. There is a mirror site aniwave.se
