ThinkFree Portable Office for U3

September 20, 2007 in 4 out of 5 stars, A piece of software, Hosted "Office"

What is it?

ThinkFree Portable Office for U3: A portable, zero-footprint, Microsoft Office compatible office suite you can cart around with you on a U3 USB drive. It includes Write (MS Word clone), Calc (Excel), and Show (PowerPoint).


Who makes it?

ThinkFree, Corp.

Why is it the killerest?


The U3 technology is nifty and this is a perfect use for it. It's like having your own private mini-computer with an Office suite that you bolt onto any computer you travel to. It has strong compatibility with MS Office, a beautiful clean user interface. 1/10th the price of MS Office. Surprisingly lightweight. Secure. Theoretically leaves behind no trace on the computer you hook into (which is usually true as long as you remove the U3 drive properly).

They've got versions that'll work with your iPod. Plus the obligatory hosted version, and even a server version, and a desktop version.

What could be improved?

There are a few UI differences in the Office software that take some getting used to.

As a company, ThinkFree is going in so many directions their marketing is confusing.

Windows Only (because of the U3) but they have other versions (non U3) that are compatible with PC/Mac/Linux.

How much does it cost?

I like this but is it not similar to - all of that is free. I even run a Photoshop (the gimp) off my USB drive as well.

Just curious - maybe the thinkfree people could explain the USP of their offering?

I wonder how this compares to OpenOffice Portable (, which is also MS Office compatible, but, is also FREE!

I have downloaded the trial version but it does not support Office 2007 documents. Any plans to update the program?

Why not OpenOffice Portable? AbiWord? StarOffice? Or even online services like Google Docs? The only office suite worth paying for is MS office, and even then only because it is the standard for great publishing.

once it involves style, there ar extensive giant chrome grille, giant headlights, equally giant taillights and chrome lines on the rear. Like most Chinese cars, the wheels look too little.
