content: I purchased three Rex's for myself and two other peopleon the advice of my friend who liked the product.Within a month, all three Rex's broke. The product is terrible! I was attracted by the product's low price and miniature size which still makes it attractive. However, I warn that the size actually becomes a big problem because it breaks VERY easily and don't be conned into believing that the product is a great fit for your wallet because it WILL break if you leave it there. The Rex comes with a hard plastic shell thats poorly designed so its hard to put in and take out of and considerably adds to the Rex's size so it no longer fits into your wallet. For the budget conscious, I'd strongly recommend paying a little more and buying the palm m100 or Handspring Visor - those will be so much more worth the purchase if you aren't too qualmy about the size. In any case, the Rex doesn't nearly compare to these in terms of functionality or ease of use.
