[Parameter] Chat Clients [Galaxy Tab] GTalk is in built and comes with Voice and Video capability which is simply great. Unlike iPad you don’t need to get any additional app.Skype has an application for Android and it works great.Score: 10 [iPad] 
There is not native chat client integration. However, the app store has a couple of clients that provide apps for chat clients easilt. IM+ is one of them which is very easy to use.Video clients are also available seperatrly. iPad does not have a client for Skype but you can use Skype app for iPhone on iPad and it works fine. I did not test the video but voice chat is great.Score: 8
