Hmm... try to contact the seller about the shipping.
I can tell you from my own experience it's a big improvement and one of the reasons I want to get rid of the HDD's. Mine is a heavily used ipod 60gb when I bought it from somebody and I sure believe the battery is still the stock battery from the original. After I swapped the hdd for the CF, I can get 20 hrs of playing time for FLAC's from that old battery. I listen to music a LOT everyday and I was sick of charging every a few hrs with the HDD's.
With said, the ipod 5.5g 80GB and classic 7G have much better battery performance even for the HDD's.
I Will. did you also use the same battery?
do you have another CF Card to test it out?
since you're using mSATA, so I assume you are using the stock FW instead of RB, are you using the US FW?
