Seagate GoFlex Satellite

Pros: User friendly interface, Good WiFi streaming with my iPad or iPhone.

Cons: Extremely poor battery life, Need to attach adapter to connect to USB, USB cable is unique to this product. Charging cable also unique to this product.

Summary: This drive performs very well with my iPad and iPhone. I "upgraded" to this from an Airstash which worked pretty well with my iPad, not at all with my iPhone, and was limited to max 32 GB SD cards so if you wanted to take a lot of movies with you required quite a few cards as well. I thought this was a solution and it would have been were it not for the lousy battery life. I fully charged this drive right out of the box and transferred some videos. After a full charge I watched about one hour of a movie and then shut it off. The next morning I turned the unit back on to watch the rest of the movie and the battery was almost depleted. That is in my opinion just ridiculous and makes it useless for any flight lasting over an hour or so. My Airstash lasted WAY longer.
Adding to the problem is the charging cable which unlike most things these days is unique to this drive instead of having let's say a micro USB port to charge with. So this is one more cable and charger you have to carry around when you travel.
Thirdly, in order to transfer files from your computer, again instead of a standard or micro USB port there is a clumsy looking adapter which has to be plugged into the end of the drive after removing a cover which looks like it would be very easy to break. This adapter comes with a detachable cable and again this cable is unique to the product. The third thing for me is no big deal since I only use this to watch movies, but if you are using this to travel with other types of files and need to transfer files in multiple places, then this is another cable and adapter to carry. The drive will charge off of it's USB connection. I just don't see why Seagate could not just put a standard or micro-USB port on the unit for charging and file transfer like the Airstash.
Overall, I found the Goflex a great performer in terms of actual streaming of media and the user interface was also great, but poor battery life and the lack of cross-compatible cables for file transfer and charging limit it's usefulness for the traveler.
