I use Tweetie on the Mac as my primary Twitter client, despite its long period of neglect. But now that it looks like it might actually become vaporware (despite assertions to the contrary), I’ve started to look elsewhere. That’s why I was thrilled when I saw the Iconfactory’s blog post today previewing Twitterific 4.

I’ve used Twitterific in the past, both on the iPhone and on the Mac, and I always appreciate the attention to detail Iconfactory puts into its UI design. But the app never felt robust enough for me, especially as a user who needs more features for managing multiple accounts. However, I’m not a fan of TweetDeck, which, though powerful, frankly just seems ugly and cluttered.

Apple’s $1 billion data center in North Carolina made headlines when the project was revealed in May 2009. New reports indicate that the facility is set to open for business “any day now,” according to local officials talking to Data Center Knowledge. It also looks like additional construction might double the facility’s size, as recent rumors had suggested. But what is the size increase for?

Recent speculation by Apple analysts suggests the company might be working on a 7-inch tablet to stay competitive with the incoming Android crop of devices sporting a similar design, like the Samsung Galaxy Tab. Our own Om Malik agrees, and for good reason, but I think otherwise.

Cost

While it is true that a 7-inch device would keep production costs down and allow Apple to drop the price of its devices further still, Apple doesn’t have anything to worry about yet in terms of being priced out of the market it essentially created. PC World recently compared prices between the Apple iPad and the Dell Streak, and found that the iPad came out the winner. Likewise, it will probably undercut the Galaxy Tab, though carrier subsidies on contract will make the Tab cheaper initially.
