I've been using it for 15 years. Palm is the good stuff!
3 March 2013
Summary: I bought the Palm Zire 21 to replace one that I have had for many years. It is a wonderful device and couldn't be beat in it's day, however, I am afraid it's day is about over as it is not compatible with modern computers because, the software will not sync with a 64 bit system which makes it very difficult to update. It will hold only about 650 names and addresses and of course, most phones will hold 10 times that.
Summary: I bought this Palm to get a taste (in an affordable way) for the Palm brand. It did give me a good sense of features offered by the Palm brand. I would call the Zire 71 a good Palm for a person new to PDAs. Its screen is a bit dim and does not have a back light. It is greyscale, does not have the ability to view pictures. I found the download and HOTSYNC to be difficult to navigate; even the company manual did not assist well with this. I do love a lot of the features.
Summary: Good in that it runs Palm OS 5, so many more applications are available. The lack of a backlight is a big drawback. However, the screen does well in bright sunlight--try reading a book on the beach with a color Palm. If you carry a cell phone and your Palm in the same bag, you should avoid this model. Inadequate RF shielding can cause the cell phone to zap the RAM in the Palm. I bought it because it was dirt cheap, and I use Palm devices mainly as ebook readers.
Summary: THE ZIRE21 IS A GREAT STARTING PDA WITH A LOT OF FEATURES. SIMPLE NAVIGATION AND SIMPLE TO USE. THE FUNCTIONS HOWEVER ARE A LITTLE SMALL TO SEE USING THE KEYBOARD AND TYPING MEMOS. FOR A BASIC PDA IT'S NOT BAD BUT I FOUND PROBLEMS WHEN YOU TRY TO DOWNLOAD SOFTWARE FROM PALM.COM SOME SOFTWARE SAYS IT CAN OPERATE ON THIS UNIT BUT CAN'T. IT' A GOOD PRICE FOR WHAT YOU GET,AND IT MAKES SETTING WORK SCHEDULES A BREEZE. I WOULD RECOMMEND FOR FIRST TIME PDA USER.
