Funnily enough recently I've started using tweetdeck on my phone too. I use Firefox and an addon called better tweetdeck to adjust the column width to the same width as my phone screen. There's some jank, but the value of having a Twitter client on mobile that's not the official mobile app, and not crippled like many third party apps are now, it's enough to compensate for that jank.

I would say as a heavy Twitter user my needs are probably not typical, but imo tweetdeck with its live updating columns is the true nature of the firehose that Twitter is, and I love it.
