Yes, it had a very specific redeeming quality.
Free upgrade to Windows 8.1 and then 10.
At a fraction of the cost.
Years ago I bought a legitimate retail copy of Windows 8 at a legitimate steep discount when that was the latest version of Windows released, to install it on a current generation at the time i7 CPU system I built from new parts. I eventually did the free upgrades to Windows 8.1 and then Windows 10 on that system. That was the last copy of Windows that I bought on its own.
After that, I have just bought used Dell systems that are a couple of years old which are being replaced because they are just out of warranty. They include the Windows 10 Professional license key in the BIOS, so you could look at it as either buying a computer and getting a Windows 10 Professional license for free, or buying a Windows 10 Professional license and getting the computer for almost free.
Back to USB 2 vs. USB 3, a USB mass storage device operating at USB 2 high-speed is limited to a theoretical maximum transfer rate of 53,248,000 bytes/second if it could fully saturate the bus. That is before the overhead of the USB mass storage device protocol.
Doing a very basic transfer test using winsat on a USB mass storage device that I have handy at the moment on a Windows 10 system I see a huge difference in sequential read speed between plugging the device into a USB 3 host port vs plugging the same device into a USB 2 host port on the same system, 230MB/s vs 37MB/s. Of course that is a very limited test scenario, and actual real world usage could vary a lot.
