I just received my V3. It also has a "Vizplex" sticker on the outside. I would also like to comfirm that this is indeed true. I stated in my order that I only wanted the Vizplex.

The only way to tell for sure whether we have Vizplex or not is to create a uniform experiment for each of us to measure either speed or contrast. E-Ink Inc. claims that Vizplex is up to twice as fast and privides 20% more contrast. Therefore the speed difference should be the easier one to measure. We need to use the simplest file format so that the effect of computer processing time is at the minimum. Probably a simple .txt file would be best. I have uploaded a copy of Gutenberg's "The Return of Tarzan" in text format. I suggest that we each do the following:

1. Load this book onto the external SD card.
2. Open the book at page 1.
3. Check your second hand on your watch and when it is at "12", start turning pages.
4. Continue turning pages until the second hand is again at "12". Hit the 'next page' button slightly before the current page is completely displayed.
The V3 will buffer this key and execute it immediately after displaying the current page. The V3 only appears to buffer one key maximum.
5. Stop pressing keys when the second hand is again at "12". One more page may possibly get displayed, if a key was buffered.
6. Report back to the group the page number that you reached.

I did this three times and I got up to page: 40, 40 and 41.

The only way to compare one screen to another, to determine if it is Vizplex, is to keep all other factors equal. This means that both should be:
1. The same make and model of Reader.
2. The same version of the firmware.
3. The same text.
4. The same format text file.
5. The same experiment for measuring the times.

Otherwise, it is just guess work and the difference is speeds could be for any number of reasons.
