Trowl uses Growl for Windows to do its magic, displaying your tweets in the Growl display of your choice. It's also ideal for forwarding tweets to iPhone.
Features:
• Multiple Accounts: Add as many accounts as you own, and configure each one to growl what you're interested in.
• oAuth Authentication: Connect to Twitter without giving up your username and password.
• Full Control: Ability to choose which users should have their tweets Growled. In addition, you can choose whether ALL replies and/or DMs get growled.
• Easy Access: System tray icon quickly lets you create a new tweet, change settings, silence Trowl, or exit.
• Fits your Schedule: Ability to specify how often Trowl should check for new tweets.
• Simplicity: Designed to be as easy to use as possible. For example, if you paste a URL into the New Tweet box, it automatically gets shortened by is.gd. If you use TwitterDisplay as well, you can reply, retweet, or DM directly from a tweet!
• Forwarding Flexibility: If you forward tweets to your phone, but decide you want to hault them temporarily, no problem! Trowl watches for specially-formatted DMs to yourself, and follows your orders!
I use this as my main twitter client- paired with growl for windows (essential) it gives a great unobtrusive way to monitor twitter. I can't say how it is with forwarding, but its great for your windows pc. My favorite feature would have to be the way that its never visible until you need it- to tweet, hit the tray icon, otherwise, it'll only show up when somebody tweets!
