Top 10 Apps You Can Use Just About Anywhere

Whether your must-have data lives in the cloud, on your laptop, or just on a different operating system, you shouldn't have to use sub-par tools to get at it. These downloads work where you do, and they also just work.

All of these applications can work on all three major operating systems—Windows, Mac OS X and Linux—and most can be loaded onto a thumb drive and run on any Windows system. Some can also be accessed from the web, and a few have dedicated mobile apps for most phone platforms. We've distinguished which apps work where at the front of each post. If we've missed any platforms, please tell us so (politely!) in the comments.

10. Buddi

Computers: Buddi is written with financial non-experts in mind. Sure, it can import your CSV file from a bank or financial firm, and it does all the standard financial calculations and projections. But the way it switches between money figures, and walks you through the importing and setting up of your accounts, makes it real open-source find, and you can easily swap profiles between your laptop and desktop systems, if needed. Looking for something with a bit more mathematical oomph? GnuCash has you covered.

9. KeePass

Computers, portable, phones: You use a multitude of applications and web sites that require passwords, licence keys, and administrator codes. On one computer alone, that makes it worth having a central vault for all that stuff. One more than one computer, having a consistent KeePass database is really, really helpful. Encrypt your master password database with a file only you have access, and/or a truly secure single password, and you can take that list just about anywhere—on Windows, Mac, Linux, iPhones, Android, BlackBerry, Palms, on a USB drive, or pretty much anywhere. Open-source coders love to write KeePass apps, so there's a very good chance you'll always have this clever password management system at your side.

8. TrueCrypt

Computers: TrueCrypt, like KeePass, is a multi-platform security tool for encrypting and protection files or entire drives. The software behind it is open source, and so likely to be supported and developed beyond its current version and platforms. It's "only" on Windows, Mac, and Linux at the moment, but it can be made to run portable, and its encryption standards—AES, Serpent and Twofish—are supported by many other encryption apps that can work with it. In other words, TrueCrypt makes you feel better about taking all the revealing information about yourself on your work on the road.

7. Thunderbird

Computers, portable: Mozilla's desktop email client doesn't get a ton of love these days, seeing as how seemingly everyone's doing their email thing in the web cloud. That said, Thunderbird remains the most reliable way to back up your email from any service and, in most cases, still access it when the web interface goes down. With the imminent release of Thunderbird 3, and the portable version to follow right after, Thunderbird might just turn a few more folks back to the idea of having your own email on your own machine.

6. Pidgin and Adium

Computers, portable: They're not the same program, but they come from the same open-source roots. These instant messaging clients do the yeoman's work of connecting to all the major chat protocols and helping you maintain a univeral buddy list. Pidgin does the job adequately, if without a ton of pizazz, on Windows and Linux clients, while Adium, compiled from the same libpurple code library, is written with OS X's glassy looks in mind. Both are crucial to not having to run multiple memory-sucking IM clients on all your machines.

5. Miro

Computers, portable: Miro doesn't get enough love (here or elsewhere) for being a pretty great all-in-one aggregator for all the video on the web. The open-source video player handles video podcast feeds, Hulu streams (which you can subscribe to, show-by-show, TiVo-style), live streams, local files, and anything else with moving pictures with ease and grace, and you can take it wherever you go to ensure your files can be seen.

4. 7-Zip

Computers, portable: 7-Zip doesn't have the sexiest job on a computer, but since no two operating systems accept all the same compressed file formats, it's an essential download. It tackles the RAR files that file sharers are so fond of, makes sense of .tar and .gz files on Windows systems, and has its own compression format (.7z) that's space-saving and quick.

3. Firefox

Computer, portable, and (coming soon on non-Maemo devices) mobile: Even if you don't think it's the absolute fastest or most cutting-edge browser, Firefox is safer than the well-known standard on most Windows systems, and it's customizable in every last detail. That makes it worth keeping on your USB drive as a go-to option for browsing at the in-laws or at home. With add-ons like Xmarks or Weave, it's also easy to keep your bookmarks, and keyword bookmark searches, within reach on any system. And when Firefox Mobile, a.k.a. Fennec, makes its debut on mobile phones, we might see some rather awesome synchronisation of everything, right down to the last tab you had open at home.

2. Dropbox

Computers, web, mobile: Dropbox creates a single folder that you'll always be able to get at. That folder can actually sync folders from anywhere on your system, but the concept remains the same—instant backup for anything you drop in one location, across multiple computers, through Dropbox's web site, on the iPhone, and on mobile browsers. That makes it perfect for music you love to listen to, documents you need to work on, and photos you pick up at a relative's house. In other words, feel free to stop emailing yourself.

1. VLC Media Player

Computer, portable: Managing the multitude of codecs, formats and restrictions on media files, from one system to another, is pain you don't need. VLC Media player, installed on any system, just works. It's built with the goods to process, convert, resize, and stream just about any file you can find with audio or video, and its presence on a USB drive ensures nobody ever comes up embarassed when their nephew's soccer video just won't play, even though, they swear, it worked just yesterday. For a guide on making the most of VLC's cross-codec powers, read Adam's tips on mastering your digital media with VLC.

What apps are always with you, or always downloaded, when you're switching between systems, travelling, or otherwise away from your preferred setup? Do tell us in the comments.


    Buddi link is:

    I think you messed up the hyperlink on buddi.
    perhaps you meant ?

    I agree with VLC, it's the best thing since sliced bread :P

      I have to disagree, apart from the lack of a portable suite 321 classic media player is better it can play a wider range of formats.

    Not only is VLC the best media player around but there is now an iphone app that allows you to use your iphone as a remote over your home wireless network.
