So do I (well, the Economist, NS, and a bunch of SF magazines). That's why I flip it on and sync every morning. So the wifi is on for half a minute rather than a whole day. That saves rather a lot of power.
(Of course, if I had other devices and wanted the last-read-position syncing rather than just using it as a backup mechanism, I might value leaving wifi on...)
