Don't skimp on audio. I only have one good ear, and so maybe I'm more sensitive to bad audio than most people. It's frustrating and a waste of time to continually ask people to repeat themselves when they sound muffled or like they're in a tunnel. Webcams are great for video, but universally bad for audio. I spent $100 for a nice Blue Yeti mic and it turned out to be a great investment. This is not an endorsement, just a note that I've had great success with this mic. I'm sure there are other quality mics available. The problem with the Blue Yeti mic is, it's too big to take on the road, and I cringe every time I have to depend on an integrated laptop audio or other cheap mic.
I started working from home one day in 1993 when a snowstorm backed up all the roads between home and the office. I dialed into the office with one phone line and worked a customer problem with the other phone line, and before I knew it, I had handled the customer issue and the workday was over. But I didn't need to drive home from work because I was already home.
Ten years later, I pioneered long distance meetings between military families here in Minnesota and loved ones serving our country in Iraq, sometimes in front of thousands of people, and a few times in the St. Paul Chamber of Commerce meeting room. But when I pitched using VPNs and video for business to Chamber members around 2005, objections flew fast and furious. I imagine if I had told them to get ready for a global pandemic coming in 15 years, they would have laughed me out of the room.
