Yes your correct RipRap on the Blackberry issue with the T515, BB doesnt seem to have good Bluetooth or maybe shielding when streaming music (Pandora). I get interference and timing issues (outa sync), but when I just play Music/Video from BB (Memory) to T515 all is good. Should have made that more clear in my earlier post thats its not an issue with the T515.

The T515 does have Shielding for GSM/CDMA Frequencies
Shielded design
GSM/CDMA shielding prevents speaker buzz.

Got a few of these last fling and it works great, paired with my Blackberry Curve.
Music sounds surprisingly good for size, its small and compact with nice carrying case to put it all in.
The only drawback for me was that I cant listen to streaming music (Pandora) while connected via Bluetooth. Other than that I am happy with them

Agree with that statement teetee1, low power unit to add to the network. Plus you have the option of adding/modding/hacking the device for your entertainment and pleasure

Most newer USB drives also spin down after some time of non-use so power savings is increased. I have heard most say the device is slow which compared to a full blown PC it is
but its like leaving you car idle all day and racing to/from work for 10min. Or you can ride the bus for 20-30mins, spends a little more time but saves a few $$ so I can buy more Flings

Curious what others are running (OS), mods on the device or plan on?

Here are a few links that others might find useful on this device.
