If your Laptop has wifi hotspot available you can sync the droid or tablet directly to a laptop via that connection it was one of the main features I was very impressed by for data mapping. where a phone is probably gonna run out of room alot quicker than a tablet either way having it sent to a laptop for study later seemed awesome.
Phones also are not meant for large amounts of data streaming or transferring via bluetooth I would bet my left nut with a tablet preferably duo core and a hidden obd2 to usb line running the refresh rate and delays would be hardly noticeable
I was actually able to go through and setup all my displays for vehicle before getting the adapter I think dsm addressed this by unistlling the program after downloading the proper pids and reinstalling.
