"Slowness" of the Pocket PRO
I got my Pocket PRO yesterday and I just want to comment on a particular aspect of it. I bought the Pocket PRO partially on the basis that page turns will be much faster than most other ebook readers out there. To quote RobertB's blog: "The heart and soul of any eBook Reader is centered around the controller and the processor. The speed of bringing up a book and speed of turning pages... all are a matter of the controller and processor. The Pocket PRO has the new Epson high-speed controller and a 400MHz processor (about double what the competition has in most cases)." In addition, on June 8th, he also said "page turns are a matter of 1-2 tenths of a second". (The quotes link to the relevant blog posts)
Now for the reality: my unit (and I must stress that this based only on a sample of one) does not turn pages as fast as I had been led to believe. First, according to the E-book Reader Matrix on the MobileRead Wiki, it has the same exact Epson controller as the Kindle 2, which is listed as having a 0.9 second full-screen refresh rate. Second, and to me more troubling, is that it takes at least a full second before the screen starts refreshing. I have tested this under various conditions (PDFs, TXTs, and ePUBs) and this is reproducible. This only occurs when I have been on a page for 2+ seconds. When I press the page turn button less than 2 seconds after the screen has refreshed, there is no lag of that length for the next refresh. This behavior does not happen on the Kindle 2. Do I regret buying the Pocket PRO because of this slowness? It depends on whether the "input lag" issue can/will be fixed. This is a solid e-book reader for the price point ($200) and it has a better button layout than the Sony PRS-300, which is the only other competition at that price. However, I do feel that anyone who is considering buying the Pocket PRO based on the speed of the page turns should be aware that it is not as fast as we have been initially told. I would implore Aztak (or Jinke) to release a new firmware that fixes the "input lag" issue though. Otherwise, when the price returns to $230, having an effective page turn speed of ~2 seconds would make the Pocket PRO a really hard sell. Last edited by Egbert; 09-03-2009 at 07:07 PM. |

A firmware update might be able to improve that. If they decide it needs fixing. |

I have been following the comments on the Hanlin V5 and you are not the first to notice this. It appears that the e-ink flash is quite fast, but that there is a delay between button push and the flash.
I'll cross-post this question in the Hanlin forum, but I'm curious if the users of the OpenInkpot firmware have noticed a similar delay. MLH |

The natural of the eink is that the only power that is needed to to open the books and turn pages. There is no refresh of the display and yes the reader will go to sleep to save the battery that is how you get the 7 or 8 thousand page turns out of the battery. The slowness is not noticed for normal reading and normally you would not even be able to turn a page of a paper book as fast as the ereader can. I have the Ezreader and it I believe has a slower controller than the pro.

Too bad. I was going to purchase one today. I will have to wait now.
Let's see what other people say when they put their hands on it. It may just be a quick fix. Last edited by wayamauro; 09-03-2009 at 07:39 PM. |

Does it come from reading off the SD memory card or the internal memory?

not sure if you saw it, but there was someone else commenting on the speed of page-changing, it was also in the astak subforum. One person's PP was able to change pages in less than a second while the other persons's took about 2 seconds. Not sure why these differences, but it may be seen with only some devices.... I hope I get a speedy one :P (tomorrow )

Apologies. In America, and possibly other English countries, little boys were commonly taught to call their penis a 'pee pee', or 'wee-wee'. That's one reason why the Nintendo Wii was commonly ridiculed when it was first released here in the US.
So, now here you tell us that someone's PP can change pages in a book in under a second. That, mi amigo, is what I call talent |
