Software Recommendations

Speaking of reinstalling, what applications do you have to have on your computer?

My list, in no particular order:

• Mozilla Firefox with Mouse Gestures add-on
  I’m used to it, Chrome installs per user instead of per computer which irritates me and has no mouse gestures, Safari also has no mouse gestures that I know of — please correct me if I’m wrong, cos it is the prettiest, and I dunno, I never got used to Opera.
• Thunderbird with Lightning add-on
  Email + Calendar with google calendar sync and no Outlook
• Symantec Endpoint Protection
  For antivirus because it’s licensed by work. But I’ve heard good things about Microsoft Security Essentials, so I would try that if I needed one for free because I wouldn’t pay for antivirus at this point.
• Adobe Acrobat Reader
  Not cos I like this program, cos I don’t. But I need to view pdfs sometimes, and the other viewers I’ve tried, like Foxit, didn’t always display everything correctly.
• PDFCreator
  To make pdfs
• Digsby
  For email notification and IM
• Picasa
  3.5 has name tags! Very spiffy! And it’s easy to use.
• Flickr Uploadr
  I need to upload photos.
• SSH Secure Shell
  I need to find a replacement for this, so suggestions welcome.
• iTunes
  For my iPod Shuffle.
• Adobe Flash Player
  I don’t like this! But Flash is all over every restaurant’s site and I need it for YouTube, to name just two things!
• The Sims 3
  I have a mild addiction. I blame Al and Julie cos they got the game for me (thanks guys!), but if I’m being truthful, I have been addicted to previous versions of the Sims, so I’m not sure I should really be blaming anyone. I try to only play on weekends, but sometimes I slip.
• Microsoft Office
  For when my sister sends me spreadsheets of what beauty products she’s buying and says I can add on what I want. :D

That’s all I can think of for now. Any recommendations? What do y’all use? :)
