I have been working on a small project lately that is an iPad app. It's a simple twitter client that filters out tweets with URLs and lets you conveniently browse them.

My question to you guys:

1) If you had an iPad (or will have an iPad very soon), would you find it useful?

2) What features would you look for in such an app (may be you'd want to be able to retweet the message, send the URL to Instapaper, bookmark the message and so on ...) ?

3) How often do you go through feeds from your twitter lists? Would some kind of lists integration make this app more useful to you?

4) Would you consider spending 99 cents on an app like this? Or, would you rather invest on a full-featured twitter client for the same price?

Any comments or suggestions would be appreciated.
