Mac: As the popularity of the Mac platform increases, so too does the risk of malicious attacks. Doorstop X offers a reliable solution, providing an extra layer of protection for your Mac. The firewall has been specifically designed with Leopard users in mind, and features an easy-to-use interface, which displays security information and settings in a series of window panes.
iPhone: TweetDeck is one of the most popular desktop Twitter clients out there – and at long last an iPhone version of the app has arrived. It hasn’t half bad either. TweetDeck for iPhone displays everything that’s going on on Twitter in a highly organized way. As with the PC and Mac versions, TweetDeck for iPhone uses a system of columns to make it easy for you to track who’s doing what.
Windows: Singing along to your favorite bands is fun, provided you know the lyrics. And if you don’t, let LyricsFetcher do the hard work for you. This app scans your music library in iTunes or Windows Media Player, finds the lyrics to all your songs in the blink of an eye, and pastes the information directly into the files’s ID tags.
