Some of those issues are addressable, even though they definitely suck, depending on how badly someone wants to swap to Linux. I have a PC I connect to my TV, and while it's built in wifi doesn't work on linux, I was able to buy a PCI wifi card and put it in, which works. You can do similar for Bluetooth. Currently I just use it over Ethernet. For laptops, it's a pain but there are USB wifi/bluetooth devices you can get. Fingerprint readers are tougher, I believe, but I feel less critical. Either way, use what works best for you!
