ThinkfreeFox is a Firefox add-on that lets you view office files (.xls, .doc, .ppt, and others) inside Firefox, without the need of having an office suite installed in your computer. After you install this small extension, Firefox automatically adds an icon on web pages to let you view any of these files with a single click (see image below). Your file will be opened with ThinkFree viewer, that runs on ThinkFree servers.

Based on my tests, I can say the experience is very smooth and the formats were kept for .xls and .ppt. On the .ppt case, even the slide transitions worked really well.

ThinkFree is one of the best online office suites available, along with Google Docs and Zoho. They are around for a while, and offer a very robust and similar alternative to Microsoft Office.

ThinkfreeFox is still on experimental phase and can be downloaded here.

Sumo Paint brings different brushes, filters and features and will let you start painting in just a few seconds. The application loads incredibly fast and it's hard to believe you are not using a desktop application. They also provide an image gallery with really high quality pictures created using their tool.

One of the best image editing software I've tried so far. Try Sumo Paint here.

It offers 4 applications: WebSheet, WebWriter, Browser and Calculator, and it has a dynamic panel on the top, that changes to reflect the app being used. You can also stack or cascade windows and the interface is very user-friendly.

As far as I could see, Peepel doesn't have the same sort of features available in Google Docs, Zoho or ThinkFree. It also don't have a presentation software. However, if you are looking for a minimalist and creative tool to manage your basic office needs and coolaborate with co-workers and friends, I recommend you give it a try.

Peepel is optimized for Firefox and is free. Access Peepel here.

Issuu provides a very robust platform for you to upload and read your documents in a very stylish and practical online reader. The ability to flip pages like an online magazine turns the experience into a pleasant read.

You can also have access to the files uploaded by others, categorized by topic, so it is also a great library to find interesting documents, like the one I embedded below:

Zoho offers an extensive portfolio of online applications, including a very complete Excel-like spreadsheet program. It's called Zoho Sheet.

Zoho Sheet is not alone in its market, and competes with products like Google Docs and Thinkfree. However, having used these products extensively (and I can say they are great), I was very impressed with Zoho's interface, ease of use and functionalities. A few years ago it was hard to believe that one day an online app would offer a similar experience to Excel. However, with the recent introduction of Macros and Pivot Tables, this possibility is becoming more and more a reality with Zoho Sheets.

Zoho can import many types of files (including .xls and .ods) and offers real time collaboration, as its competitors. But they offer some other goodies as well, such as different color themes and templates. It also offers good exporting options, such as the ability to embed your spreadsheet in your website, as you can see below.

Another great benefit from using Zoho is its integration with the recently launched unlimited storage solution Livedrive. You can simply upload all your .xls files to Livedrive and edit them online, without the need of downloading or having Excel installed.

Access Zoho Sheet here.
