Reasons Why NOT to Make Entire Site Secure (SSL)

Hi,
I've researched the reasons why you would want to make certain pages of your site secure with SSL. However, I'm wondering if there are issues making the ENTIRE SITE secure. We are collecting information with cookies but do not have a user login. From what I've read, our site would still be indexed by search engines if it was all https. Does anyone know of major issues with this?

Thanks.

When a page is secured with SSL, the browser doesn't cache anything on the page. Which would be huge bandwidth increase for you, since every page view would require re-downloading all the images and other content. That would be the biggest reason.

If your entire site were being run through SSL it could cause problems with people trying to type in your URL as most people will type http and not https.

...the average user, if they type anything but "whatever.ext", will rarely type http://, but only www. http:// would really only be used by people linking.

And where do I find the statistical data that computed this average?

Hmm, I think it's fairly obvious that no one types http://. I've no data to back that up but it's common sense surely?
