I would love to use the extra battery life for the on-the-go lifestyle I lead: Twitter, Facebook, foursquare, Brightkite, et al. And let's be honest, holsters just look slick with a suit so I would be able to keep on-the-go in style!

I would use the extra battery life to read TUAW on the go more often throughout the day and retweet the articles to my less blog-savvy friends!

Finance

I want to create a beautiful yet robust money management app. I like Pennies but feel that it lacks functionality. I think being able to track transaction from your phone/iPod right when you spend that money is a necessity.

"Personal Finance 101" - Teaching the average low to middle class American better strategies for managing their money.

or

"CollegeMac" - Talking about how to make your schooling as easy as possible using the plethora of resources available on a Mac.

I would love one!

In my binder, about 250ish and it is maxed out. Scattered across my office and house, about another 75-100 or so. I could really use this darn device.

I have wanted one since I first read about it here on TUAW but it's just a bit out of price range for me so here's to hoping I'm a winner!

That's what Twitterific has done. Excellent model in my opinion. Have one premium edition (ad-free and hopefully some additional features) and the basic edition (ad-supported, fully functional but maybe missing some "premium" features).

This is especially a good model for the AppStore since there is no way to trial anything.
