tweetie 2 buy or not?

I just want to check what’s with it, and to try the feature which can save link to instapaper even offline. I have the first version tweetie which I do not really use. And, I do not really tweet much from ipod – touchscreen makes typing such an effort. Thus, I am having second thoughts of buying it. Though, it is only $2.99 or around 150 pesos, not really that bad.

Point is i am really really itching to know what is inside it. And, i do not see it a valid reason to spend 150 pesoses just to satisfy that itch.
