Google has never ceased to amaze me. I am proud to say that I'm not a Yahooligan, rather I dwell in the recesses of Google scientists. Anyway, back to business. I'm currently tinkering with Google Docs. Years ago, the interface and its usability sucked. MS Word or Thinkfree was more my (word-processing) game. But here comes the newly improved suite; you have templates here too. Additionally, you get support from different file formats like PDF and xls sheets, which is a very good thing! And I might add, you can work offline by installing the program on Google Gears.
For today's increased productivity level, I give G Docs, *****.
