Five things you may want in your next smartphone

5. Dense displays
720p is all the rage these days with smartphone displays, and it's definitely something to look for as The Age states. Higher density displays look crisper and sharper, so anything over 300 pixels-per-inch is adequate for pixels to be indistinguishable to the naked eye (at a reasonable distance).

However 720p is not a definite "must buy", as phones with smaller displays, which some people prefer, don't require this resolution to achieve a good pixel density. 1280 x 720 delivers over 300 ppi right up to 4.9", but 960 x 540 (qHD) is fine for displays smaller than 3.65" and 800 x 480 (WVGA) is good under 3.1". As long as the smartphone you choose reaches the magic 300 ppi, you should get a very crisp experience.
