An easy way to see if a two page display is for you is to download the PC ereader from ereader.com and see for yourself.
You can drag the screen to any size you want as well as select fonts and margins. The link is below.
Take any non DRMed file and let Calibre convert it to PDB and open it with the ereader. All the settings can be found by clicking View>View Settings
