iPhone: The official Twitter client for iPhone is probably the best you’ll find in the App Store. Tweets can be viewed, links opened, retweeted and replied to as usual. Swipe a tweet and a menu of icons appears giving you the full range of options. Writing a tweet is simple, and a menu can be opened to add hash tags, photos, users, video and more. The latest version fixes some bugs, improves security and adds support for iOS 4.0.
Windows: If you want to fully protect your system, Kaspersky Internet Security 2011 is an excellent choice. This comprehensive suite includes all the tools you need to stay safe from viruses, worm, hacker attacks, spam, phishing and other possible online threats. It also includes a sandbox environment to test apps safely, parental controls and a gaming mode.
Mac: Optimizers and tweaking software abound on Windows, but Mac users have far fewer choices to speed-up their system. That’s partly because Macs generally self-maintain better than PCs but if your Mac is slowing down, you might find running MacKeeper (now updated to version 0.9.4) helps breathe new life into it. MacKeeper is an all-in-one solution that includes hard drive cleaning tools as well as backup and shredding utilities.
