I purchased my iFD440 in July and love it. It works great and is a great replacement for the 430w. The touch+button function is amazing, I like the feel, resolution, and overall functionality. I strongly recommend it to others on my facebook group. However from a function standpoint there are a couple enhancements I'd like to see. Giving some more customization to the home screen like changing the range ring, or making the 'direct to' command take less clicks in case of emergency would be welcome features. I'd also like to see the display a bit taller, as there is wasted real estate above and below the screen. Lastly, I have miscellaneous issues with the iFD100 app that although a motivator for buying the IFD440, now in actual use gets minimal attention. Thanks!
