For me, I need a centralized music player/storage unit that is capable of playing lossless files with high quality. So the internal 2TB drive option in the Olive One is very appealing to me, since my music library is fragmented across about 6 different hard drives and devices. An SD card or external USB drive would just be another peripheral that would have to be swapped out eventually once space runs out, which it will for me. I used to work for a record label and DJ every weekend, so I'm not a casual music listener. I also like the option of controlling it with an iOS device.
Also, I was wondering if you guys think this would be a better DAC than the one inside the Olive. For about $120 bucks, you get this external DAC with digital SPDIF in and stereo RCA out, with an external power supply. This might be a solution for people who don't want to run their system through a 3.5mm output jack.http://us.hifimediy.com/index.php?route=product/product&product_id=51
