Well, we've done it again. We've squandered away another perfectly good hour week... wait, no. That's something else. But if you haven't squandered away your week on Download Squad, here are some of the stories you may have missed.

• Flipping the Linux Switch: Cairo-Dock is pain free eye candy
  Want to run Ubuntu, but like the look of OS X? Cairo-Dock is an OS X-like dock for Linux.
• Microsoft: Think twice about IE7 before upgrading to XP SP3
  We're going to go out on a limb and assume this doesn't affect a lot of people. But if you want to upgrade to Windows XP SP3 and use Internet Explorer 6 (because you're only cutting edge when it comes to operating systems, not web browsers), here's a tip: You will not be able to downgrade from IE7 to IE6 unless you install IE7 after SP3.
• Filemail: Email files up to 2GB
  We're always on the lookout for new ways to get around the 10-20MB file attachment limit imposed by most free email service providers. Filemail is a new service that lets you upload files up to 2GB to share via email. You can also adjust a variety of settings, or pay for a premium account if you need to upload even larger files.
• OpenOffice.org 3.0 beta now available
  The next major OpenOffice.org release isn't due out until this fall. But you can download a public beta of OpenOffice.org 3.0 today. The new version includes a handful of new features, a bunch of bug fixes, and a native OS X client.
• Hahlo 3.0: Twitter freak's new best friend
  Hahlo 3.0 might just be the best Twitter client we've seen for the iPhone. It's fast. It's pretty. And it supports practically every Twitter feature you could want in a mobile client.
• Puppy Linux 3.0 released: Linux for your flash drive
  Puppy Linux has long been one of the most popular "portable" Linux distributions. You can install Puppy to a flash drive and carry it with you to use on practically any computer that can boot from a USB device. The latest version includes a new theme, better hardware support, and some shiny new applications.

The whole point of Twitter is that it's fast and mobile: if you see something interesting, you can post about it right away and see the responses right away. That's why it's been so frustrating that no Twitter client for iPhone and iPod Touch has distinguished itself with a good-looking user interface and all the features the advanced Twitterer demands. Well, problem solved: meet Hahlo 3.0.

We've been playing with the beta version of Hahlo 3 for a few weeks now, and it has everything iPhone Twitter apps have been missing. The navigation is quicker and more intuitive than in previous versions, user profiles look better, you can view your direct message outbox, and following and DMing people from Hahlo now works flawlessly. This stuff should be the bare minimum for a good Twitter client, but there's more.

Hahlo now has built-in support for Summize Twitter Search, and displays search results within the Hahlo interface. This is invaluable if you're as popular as we at Download Squad are (you're following us, right?), because you'll inevitably miss a few messages and find it handy to catch up by searching your username. Before Hahlo 3.0, lots of messages went unread, from friends who buried our @names in the middle of a tweet -- now we're not skipping a beat.
