When I was working I had access to wireless broadband cards and accounts. Every time there was a new Ubuntu or Mint (along with a number of other distros) I would load it onto a spare machine in the hopes that they had added broadband support.
Each time I would see that they hadn’t and I would walk away disappointed. Oh, they would claim that it would work but what they offered was a convoluted kludgy mess.
I have since learned how to tether my phone to my laptop for on the road internet access. It’s not as efficient as the internal broadband cards but gets me there.
My chief complaint about Linux machines remains working with Windows machines on a home network. It isn’t as seamless as working Windows to Windows.
