Many of my ebooks are anywhere from 50 to 350 Mb. That adds up when you want to load many of them. The downside of course is that you need a good Net connection, unless the Calibre Content Server can be configured to do some kind of 'trimming', while serving the ebooks over the wire.
Also a content server mitigates you having to manage and synchronise your ebooks in multiple places. You only need to manage one library. Although I guess any sync application can work just as well for this.
They contain a lot of colour images and diagrams. Books on biology and art. Granted other topics including fiction are usually in the ballpark of a few megabytes.
