essential must have software for a new thinkpad t61

[fr0zenmon]

what software should i consider adding to my tp? Leave no stone unturned. I am looking for field specific software too, law, science, writing, business, office, multimedia and web. I am being general purposely.

While we are at it where can i get latest software reviews? I found trustedreviews.com and consumersearch.com and they are good but sparse converage. Is there an engadget equivalent for software.
