Summary: Had the 1940 but, with the addition of integrated Bluetooth wireless communication and a faster processor, the h1940 is what I really needed. So much power in a machine that weighs just 4.37 ounces and is very small (4.46 x 2.75 x 0.5 in).
Excerpt: First of all, for anyone looking to buy one of these, it's worth noting that this little gem is EXACTLY the same as the iPAQ H1945. The only difference between the H1940 and the H1945 is one was originally sold in the USA and the other destined for the European market.
Excerpt: The iPAQ 1940 is a very handy little device. I personally use it to organise my day and to listen to music. I purchased this about three months ago and have not had any service problems. I have not had to contact HP with any problems regarding this PDA.
Excerpt: The HP iPAQ h1940 is a very powerful Pocket PC; the h1940 is smaller than other iPAQ models which makes it more portable than ever. The official dimensions are 2.75 in x 4.46 in x 0.5 in (113.3 mm x 69.8 mm x 12.8 mm), weight 4.38 oz (124 g) (including battery).
