It’s hard to ger rid of the FUD from the past. There used to be a time where you were happy to be able to boot your computer. Sound, networking (ha, forget about wifi), it was all a gamble or a hassle to get working. To keep it that way Microsoft somehow convinced the industry to make Winmodems. They intentionally crippled ACPI to only work with Windows.

Then came the intermediate time where it was 50/50. Maybe you could get the wifi working with the Windows driver and some ndiswrapper magic. Maybe the hardware vendor had some driver that would only work with exaxtly one kernel version. Before ATI was bought by AMD it was better to buy nVidia because their drivers didn’t suck nearly as much as ATI’s.

And now at least big vendors add Linux drivers before their new hardware even hits the market. Most hardware works out of the box. Even small specialised stuff. Printer? Scanner? Your system has it configured before you even thought about using them. And ACPI is so crippled on Windows that it can’t even suspend a laptop properly half of the time. But Linux does it like a champ!
