If you're a BlackBerry PlayBook owner and avid Twitter fan like myself, you're certainly not a fan of the fact that there are no Twitter clients currently available on the RIM tablet. I've searched high and low for the best part-time solution, and the best I have found thus far is a site/webapp called Hahlo. By navigating to hahlo.com from the PlayBook we browser you can be up and running in just a minute or so. Log in with your Twitter credentials, set a few options and you're ready to rock. Hahlo has a bunch of great settings worthy of a stand-alone client like auto-refresh, timeline options and more. You can view all of your messages, mentions and lists in Hahlo as well. Leave it open in a browser window and it will refresh at your set interval, showing new tweets in a different color for easy recognition. For now Hahlo is a pretty good solution for our Twitter woes, but here's to hoping that we see a much better client for the PlayBook very soon. Head to hahlo.com from your PlayBook to get started. More screens after the break.
