I use my cheapie android tablet almost exclusively for TBT as my phone was in for repairs when I joined and has only just been replaced. I would normally have used my iPad as the bigger screen size suits the layout here better, but that android tablet was my temporary phone for a couple weeks and was all I was using. My iPad is too heavy for me to use easily anymore as the lifeproof case weighs it down significantly and it is quite unwieldy.
Now that I have a working phone back and can return to normal browsing (mostly on the phone with iPad for games or viewing sites and content the phone is no good for) .... I've found I still keep coming back to this dinky little tablet instead. Ah well. It's good to have options!
for me, the main thing i use to go on tbt has changed several times since i joined here.
at first i used my wii u and my phone to go on it, though i used my wii u a lot more because my phone is super slow. once i got my tablet in march, i stopped going on tbt on my wii u and my phone because my tablet's internet browser is way better imo. but for the past few weeks, i've gone back to going on tbt on my wii u because the charger for my tablet broke.
I use a laptop. 2 months ago I used my Wii U because my old laptop broke, and I didn't have a phone at the time, and still don't. I have a new laptop now and its good.
