If you are getting nervous about your data being in the cloud, want to switch services away from Google, or are just looking for a quick and easy way to make a back up copy on your hard drive (always a good idea), Google has just made the process pretty simple for you.
""Convert, Zip and Download" now joins dozens of other liberation features across our product offerings, ranging from Blogger's full blog downloads to email export from Gmail using IMAP and POP3. The feature lets you bundle your Google Docs in a format of your choice (MS Office, Open Office, PDF, etc.) and download them as a zip file. No longer do you have to download each document individually, which can take a lot of time if you have hundreds of documents like I do! All you need to do is select the relevant Docs, click on "Export" from the "More Actions" menu and download them in one go. (Check out the Google Docs Blog for more details.)"
