Loving it!

I can see why Digital Science might feel sore about the degree to which iElements might seem to copy their Elements, and making the name so similar acknowledge this in a way that is either cheeky or ingenuous according to taste, but from a user's perspective iElements is actually rather good: it does not have quite the same depth of info as Elements, but it improves on the interface to my eye, contains some informal info (history and images) that elements lacks, has a better search (by name as well as symbol) and costs very little. It is also more up to date: Elements has not been updated in two years, and lacks a few new element names.
