I like the idea behind Dlna but can't think of a time I'd actually use it. I have 4 phones an HTC trophy, an iPhone 4, a Nokia E7 and an LG P500. I use the P500 as customizable home screens is the big thing for me.
I use the smart phone mostly for calling and emailing, I love being able to open all the attachments and viewing them, properly. The other big thing for me with Smart phones is the cloud integration be it iCloud, Google apps, or windows live, having all my data auto syncing across all the platforms is great. I personally don't take photos often or play highly graphical games so don't worry about other aspects of the phone.
So my Question is to you what features do you actually use, or being geeks do you just like to brag about the big numbers ( no shame in that, we all do it :) )
