Though I’m not a rabid Linux person, I use it on occasion. The Linux desktop has existed for years now. You could get Dell’s with Linux pre-loaded for many years now.
I have been a Linux Admin for decades, but my desktop of choice has always been mac. But before you all get out the pitchforks... I have switched to a Ubuntu desktop. Easy transition now that most Microsoft business products either work native, or are web based and somewhat usable on Linux.
