I used Casio's Cassiopeia E-125 as our Pocket PC-based e-book reader. Not surprisingly, the $549.95 Cassiopeia's size works for and against it. The 8.8-ounce device is certainly painless to carry around. Although it measures 3.3 by 5.2 by .78 inches, its 4-inch diagonal screen is small for reading a book. Microsoft's ClearType technology provides clear, easy-to-read characters, but only 15 lines are visible at a time. That's a lot of page turning, which is done by pressing the large button on the bottom left of the device. You can choose between small characters or large characters, but you get significantly less text on a page with the large size: 11 lines, with four or five words per line.

The brightness and contrast controls (Start/Settings/System/Brightness) make it easy to adjust the screen in a variety of lighting conditions, but it's difficult, if not impossible, to read in direct sunlight. Of course, with a brighter the screen, the battery drains faster.

You'll also want to reset the Auto Dim function (Start/Settings/System/Brightness/Auto Dim) if you're planning to read for any extended period of time. Otherwise, the screen will automatically dim before you reach the end of a page. The default is 15 seconds, but I found that 30 seconds is ideal.

Features that resemble some word-processing functions are a good argument for e-books, particularly for the scholarly reader. With Microsoft Reader, you can highlight sections, add bookmarks, insert drawings, search for words and copy text. You can choose to start your next reading session on the first page, the farthest read or the spot where you most recently stopped.

Another advantage of the Pocket PC is its audio capability. With Audible.com and an audio e-book, you can listen to a book through your Pocket PC; add a set of headphones for a private listening experience.

Are Pocket PCs a good way to read e-books? You probably wouldn't want to purchase one simply for that purpose, but if you already have one or need one for other functions, it's not a bad way to go. Still, even those with an environmentalist's viewpoint will likely conclude that e-books won't take the place of paper books yet. -- From Winmag®

Customer Reviews

The Casio e-125 represents the best of whats out there for Pocket PC platforms.
Amazon Customer
Plus, I HIGHLY HIGHLY recommend that wherever you buy your PDA, online or in a store, you go in person to a store to try out the different models.
With all this said, I still think that buying this PDA, for novice users or experienced ones, is a great thing.

Do you still use one of those old monochromatic dumb terminals at work or at home? Of course not, I didn't think so. Then why would someone want to use a plain Palm Pilot or a Visor, when you can get this little wonder for a (little more)?
I got my Cassiopeia 125 about a month ago and I cannot imagine life without it. I went through 3 Palm Pilots (including the color pilot) but this little gadget is the BEST. It is not a handheld device, this is COMPUTER. No kidding!
You get much more than just a gadget for appointments and phone numbers. You have a windows operating system (there is nothing new to learn, everyone knows windows by now) and you can run such programs as Excel and Word in an incredible color display. You can also add a wireless internet connection in the place of the memory card and access the interent at high speed. With the 125's bright colorful screen, you will feel like surfing on your desktop (Ok, some extra scrolling IS required). You can receive and review all your emails when you synchronize with your computer, or you can go with the wireless connection and work directly from your Cassioppeia, sending and receiving emails.
The 125 comes preloaded with 32 mgbytes of memory but your can upgrade to 1 Gig (yes you read that right) since the Compact flash slot is compatible with the new IBM microdrive. Jornada CANNOT do this, and the Compaq Ipaq needs expensive and bulky add ons to achieve this effect. Think about it, 1 gig of memory can hold almost 20 hours of MP3s. I have been using mine as an MP3 player on the subway, on the way to work, and I love it. Be warned though, you need a Compact flash reader for your computer to tranfer the music on the card. Doing that through the 125's craddle is time consuming.

The Casio e-125 represents the best of whats out there for Pocket PC platforms. The size and architecture are very sleek and easy to handle. Battery life is about the same as the rest in its class. (6 hours continuous use, or a few days with limmeted use) It is best to let it sit in the cradle at night to charge each day then generally you don't have any problems with battery life. You will want to seriously consider the extra battery pack for those long flights from L.A. to New York. The e-125 is the best solution for someone interested in the entertainment available for PocketPC. For someone who wants to use it for an MP3 player the Compact Flash memory upgrade is a must. I recommend the IBM Micro Drives, they are a little more expensive but well worth the 128mb to 1Gig of memory they provide. You can easily install all your programs on the micro drive and leave the system memory for running the programs. Media Player 7 for PocketPC is a must, so is some kind of task manager program. I recommend PocketNav which is a freeware program you can find at Tucows Pocket PC Download site. ActiveSync 3.1 is good but requires a little Patience as it is not yet perfect. You cannot sync with anything but Microsoft Outlook and the sync cradle itself leaves much to be desired. Expansion for the e-125 is one of its best features. The Pocket word and Pocket Excell programs are good but they still don't support many of the features that the standard versions support. The callendar program works great and the alerts for the internal speaker are very usefull. To add any Compact flash devices it does not require any extra sleeves or jackets like the Ipaq 3650.Read more ›

The E-125 by casio is far most a must choice if you are planning to get a PDA. Being an owner of a PDA Cassiopeia E-15 (Windows CE 2.1 - Gray scale) I actually thought of striking of the Casio Pocket PC off the line of choice such as the iPAQ and the Jornada by HP.
The reason being, I had many, too many miserable times with the screen. The display is fine but the touch screen gives me one too many problems. Every ones in a while I will be required to recalibrate it to ensure the accuracy, at times it would not even work. Enough about the bad things on the E-15. On the overall it is a great product if the problem of the touch screen alignment is resolved.
Now that I am purchasing a Pocket PC, and with 3 choices I was actually settling down on the iPAQ until I did more research on it.
I picked iPAQ initially because of it's fast processor and the great looks. However, when I did my comparisons and further research, I found that the Cassiopeia would be a better buy.
This is why :
Firstly, when you are thinking of a Pocket PC which has multimedia capabilities coupled with coloured screens and stuff, one would require a whole lot of power. Sure, the Compaq boasts a 10 hour continuous use where the Casio has 6. This is gauged from a heavy user where the owner would use the Pocket PC continuously. However, at the initial thought, the Compaq would be better in battery usage, TRUE but not on the long run. What Compaq has which is overlooked by most Compaq buyers is that the battery is built in. The battery is not consumer removable, thus, just like all batteries, the battery has a life cycle of charging and discharging, when the battery goes too old, the performance will be significantly reduced.
