Every now and then, we find our technological preferences going backwards. This happens either when the old technology had its pluses we forgot about or the new has serious deficiencies. Look at the resurrection of vinyl records lately. It's happened because digital music sounds like garbage, and audiophiles have noted for some time that vinyl sounds much more natural.
I'm feeling the same way about my phone. Never once did someone tell me they could barely hear me on a land line. No calls were dropped. I didn't lose signal. Nor did I suffer for using a land line.
In the end, it's about productivity. If I get one more call saying "Wow, I can barely hear you," or drop a call mid-question, that may be my signal to call AT&T for a land line and go retro. At least I'll be able to do my job.
