Have you ever needed to move something from one computer to another?  If so, then you have serveral options at your disposal.  You could email it to yourself, put it on a flash drive, burn it to a disc,  or upload it to an online location.  All these options are fine solutions, unless you want to update the file from multiple computers.  Each update will require you to re-email, burn, or upload and then re-download, unzip, restore, etc.  This is a time consuming process, and though this may work for some files, there is a better way to sync computer folders.

Dropbox is a online tool that allows you to securely 'sync' folders on multiple computers.  Not only does the Dropbox allow you to access and synchronize file updates on multiple PCs through an installed program but also it provides web access from any PC.  So when you save a report or document for use in a presentation you can do so on Dropbox without installing anything on the client's PC.

Additionally, you can share folders with other Dropbox users or anyone else, by providing them with a public link.  The public section of Dropbox is intened for sharing nonsecure data.  However, the private section is secured through a variety of security technologies.  Dropbox provides assurance that the files you store are safe, as long as they are not stored in the public section: "Your files are actually safer while stored in your Dropbox than on your computer in some cases. We use the same secure methods as banks and the military to send and store your data."

Dropbox has a few different levels of storage to match the needs of particular customers, but for the average user the free version will provide plenty of space. 

The free version comes with 2 gigabytes of space, but is expandable to 8gb through a rather clever referral scheme.  Each referral who signs up using your link will earn you..and them..an extra 250 mb of space.  So if 24 people sign up using your referral link you will be able to store 8gb of data in your Dropbox.

Once you have installed DropBox, it will show up as a folder in your 'My Documents' now all you have to do is start saving files to the folder from any computer.

If you want to get an extra 250 mb of storage space when you signup for DropBox use the following referral link: https://www.dropbox.com/referrals/NTY5NTAzNzI5

As a PC person, I inevitably will enter into discussions with those folks who choose Macs as there primary machine.  I admire Apple for a lot of things, and give them credit for innovation in the industry.  The iPhone was a revolutionary device whose user-friendly design and usefulness makes me a fan.  However, in the area of desktop security, Apple has been overstating the strength of their security and relying on a total number of attacks being more for PCs than Macs.  Though PCs have more attacks as an aggregate,it doesn't take a degree in statistics to realize why that might be...Market Share.

In a recent PC World article interviewing former hacker, Marc Maiffret. Maiffret says that Apple and those who buy Apple products are failing to take security threats seriously. "If they were taking it seriously, they wouldn't claim to be more secure than Microsoft because they are very much not. And the Apple community is pretty ignorant to the risks that are out there as it relates to Apple. The reason we don't see more attacks out there compared to Microsoft is because their market share isn't near what Microsoft's is."

I do not believe that a preson who buys a Mac is necessarily less secure, because though they are more vunerable to attacks, they are less likely to be a target of the attacks for the very same reason that windows is made a target.  Virus/Malware makers want to make the largest impact possible. Therefore, they target the Operating System with the highest chance of spreading their malicious code. 

I only wish that Apple would be honest in its assessment of their Operating Systems security...and stop hiding behind aggregate numbers that neglect market share.
