My dinosaur Dell laptop, and sometimes it just spins and spins when I try to post...(this thing is in such bad shape that it now always has to be hard-wired!) I'm never sure whether the problem is on my end or the site...
Also, my Samsung Tablet (a wonderful gift from one of the dogs that I babysit!)...but I
don't know how to use it very well...so, I mostly use my laptop.
