I am on my tablet now. I don't like to type a lot on it or edit photos for posting etc., but it is great for a quick browse through the forums. I have set my Opera mobile browser to a minimum font size of 15 so all text is a sensible size. The responsive site software copes with that beautifully.
If I am writing long posts, I use my 12" Windows laptop to access CC.
I haven't used a desktop PC since getting the DVT in my leg 2 years ago because I can't get comfortable sitting upright. (The circulation in my left leg is compromised so the blood pools in it. Fortunately, the pumping action of the calf muscle means that I am fine walking and cycling.)
I have tested the site on my phone and it works, but the tiny 3.5" screen is a bit tricky to click on. I haven't really felt the need, TBH. I carried the tablet with me on my recent one week cycling trip. I would rather stay offline on single day rides.
