Using dropbox as your virtual "thumbdrive" is very useful especially when you want to acces and share your files with your friends. Its free too!
For those who use android based phone, you can download dropbox apk at the google playstore. Install and log in using your dropbox account. It will synchronise your dropbox and from the phone you can share/download your files if you wish to view them on your android phone.
It is safe and fast too! Having dropbox installed, you are no longer worry about not to bring along your thumbdrive as your files are floating on the clouds
To use this service, you need an email and the skill to click "next" as the minimal requirement to install dropbox. I think that would be no problem at all....as you are so used to click "like" status in the Facebook!
I did put a link on the left column of this blog. Give it a try!
