Casio PV-400PLUS Cassiopeia Pocket Viewer Handheld Organizer

Old technology. Does not work with laptops. Missing parts.

This item has many plus points, and some drawbacks. One of the pluses is that information saved stays on the internal flash unit, and is not lost when batteries fail. Another plus is that one can keep sensitive information private with the 'Secret' feature (password protected). The 'Expense' feature (for calculating expenses) is not user friendly in my opinion. My major gripe with the Casio PV-400PLUS Cassiopeia is that the back-light stays on for only 15 seconds, and that the time period it stays on is not adjustable. Without back-lighting, the screen is not that bright (even after adjusting the contrast). To keep pressing the 'Light' button every 15 seconds is not a useful option. All that being said, the 'Memo' ,'Quick Memo' , and 'Contacts' features are good, useful features. I recommend this item to those looking for a reliable little electronic note-taker, but don't recommend it for interfacing with a modern computer, or for its any of it's other features.

This was bought with the intent of replacing my Daytimer planner. It is handy and easy to use, but I'm now thinking it will make a great companion. I still find certain entries easier and faster to do with my "manual" Daytimer. This might change as I become more proficient in the use of it, however. It is simple to use and much more portable than my Daytimer, just wish it had a keyboard :).

Great tool for keeping a calendar that can give you a "ping" for the next appointment. Not an up to date electronic calendar, but not necessary for keeping track of one's day.

Most of the reviews for this product are about 13 years old, because that's how old this thing is. I had something similar (a TRG Pro, old PalmOS device) waaaaaaay back in the day, and it was in fact quite useful. There are things I miss about it, like how it would last forever on a pair of batteries and let me take notes quickly with a stylus and their Graffiti alphabet. (Graffiti is similar to the shorthand that secretaries used to use - it's easy to learn.)In its heyday, being the tail end of the Clinton presidency(!!!), it would be reasonable to pay over a hundred dollars. Maybe even over two hundred. It probably costs less than $5 to manufacture these days. It just isn't a good value for the money, and hasn't been since... oh... about 2003 or so.If you're already on Amazon, and you want a really old monochrome PDA, they are still selling the PalmOne m500 for under 50 bucks. That's many times what it cost to make, but if your heart's desire is to have a PDA with ancient technology, you may as well get that instead. (To be fair, these things do have great battery life. My TRG Pro was a champ at that.) You might also want to look at getting a cheap smartphone or a refurbished "Pocket PC" which is a PDA running a heavily stripped down version of Windows from circa 2005.

I am a big fan of the Casio PV series- my wife bought me a PV-200 a couple of years ago, and it changed my life! It had all the features I need. I don't need email, infrared beam transport or the other bells (I have enough high tech dodads in my work), and the price was great. However, after persistent problems with the touch screen, I decided to upgrade to a PV-400 Plus. I got it on sale at Office Max for a great price. But guess what? This one not only has a very fickle touch screen but it keeps losing my data through memory problems. Casio says I have to send it to Japan to be repaired, but I think I'll just bite the bullet and buy a Handspring or Palm III this time.

Have only had my PV-400+ for a day but can already see its a very well made product. Rather than be redundant, I'll agree with all the other comments here (except that I havent tried the Outlook Sync yet) I bought it to replace my aging and now inop Sharp YO-370 (128k - how did I ever manage. Even after 6 years I only filled half of that, so I'm hoping the 4MB fo the Casio will do me for quite some time) After dropping it many times over 6 years I'm impressed it lasted this long. I used a Royal ds3080 briefly (it did not compare to the Sharp, almost identical functions, just harder to use. Just goes to show, it's not all about features; the user interface is very important too. Which is why I strongly recommend trying any product out before buying)Other than a couple of (I think)glaring omissions the people at Casio seem to have put alot of thought into this product. My biggest dissapointment (actually pretty minor though) is the limited conversion capabilities. My Sharp could convert feet to meters, liters to oz.s etc., the Casio can only convert currency. With all the memory this has you'ld think they could've squeezed a few more conversions in there. The only other complaint (even more minor) is the lack of a backspace key. Again a feature on the Sharp (and every computer keyboard in the world)if you accidentally type in a wrong letter, correction is a two step process: tap the space right before the offending letter, then tap delete. It is so much more convenient to just hit backspace.I only complain, because it is otherwise an outstanding product, though it could have easily been made perfect. So... only 4 stars **** (ps. I'm hoping 3rd party software may fix at least the first problem)

Comparing the product with others.Can't beat the price. Sometimes explanation in the manual is hard to understand. but overall it is a good product
