Having access to all of your files, emails is main advantage of webOS

What it is – a virtual machine that lives online. When logged in it closely resembles your desktop (after tweaking) including the menus and icons. In most cases you can even customize the wallpaper. Once you’ve uploaded files you’ll have access no matter what PC you are using.

WebOS/Webtop/Cloud providers – there’s probably more webOS providers than I’m aware of but three that come to mind, in no particular order are:

G.ho.st (http://g.ho.st)
GlideOS (http://glideos.com)
Icloud (http://icloud.com)

Advantage – the speed of the computer you use to access the webtop doesn’t depend so much on the processor but more on the internet connection.

Synchronization/File uploads – typically, three options exist:

1) upload files one at a time
2) upload files in batches, or
3) use the built-in sync feature that updates files on ALL of your machines. Just select the version for the PC you are currently using and download the installer. Then enter your login information and set utility options. Choose sync in both directions – set conflict resolution to keep the newest version of each file.
