Re: For any who don't already know...
It's certainly waaaay better than it used to be under IBM's remit and the early Lenovo days. I remember the P in the A it was to pull together the drivers required for a fresh Windows install (back when it all had to be done manually) on, say, an old T610. Selecting the right network drivers alone was a nightmare - have I got Intel WiMAX 6250 AGN, Intel Wireless LAN (11abgn, 11bgn, 11ac), Intel Wireless LAN (11bgn) or ThinkPad 11b/g/n Wireless LAN Mini-PCI Express Adapter II. Nothing evident on the machine itself. There are also driver selections for Huawei or Leadcore wireless drivers. The driver was also a self-executable that simply extracted all the files to C:\THINKPAD, so no downloading to a thumbdrive, it was download, run all the exe files, then copy to a thumbdrive and hope you had the right ones.
In Lenovo's praise though, they're all still there in the end-of-life section:
