I've spent a good time of today tweeting from Twittelator Pad [$4.99 - iTunes link], and I must say that I'm rather impressed.
Twittelator Pad is best viewed in landscape. On the left hand side, your timeline is displayed in a nice traditional fashion and on the right hand side is where you can access all other features of Twittelator Pad. Choosing different tabs on the bottom has nice animations that are appealing to the eye.
One of my favorite features of Twittelator Pad is that photos are embedded into your timeline and conversations. In most cases, pictures are plenty large enough with no need to enlarge them. Twittelator Pad also has a nice drafts feature that is easily accessible when you need it.
So far, Twittelator Pad has given me the Twitter experience I desire on the iPad. To see what Twittelator Pro has to offer in more detail, check out the screenshots and video after the break!
