I'm sure I'm not the only one here who doesn't want to spend $.99-$4.99 on chat clients that I use for free on my computer just to have them on iPad. What's available for browser based chat clients? I know Google Talk has a version for mobile browser use. What about the others like AIM and MSN? I looked around, but any I looked up seemed to lack a clear route to a browser based version of their chat. Has anyone found any that are available, or are the dedicated apps necessary? If you've found a link to a browser version, post it!
