Difficult installation & over complicated, too many options to start with, some not compatible with initial setup (iPad OR computer upload). Nice look to software, but unable to install initially, requiring re-boot before 'create account' was possible. Software is still slow & flaky, crashed my 2 year old iMac twice in one afternoon & the software quit with a fatal fault three times (Felt like Beta software, but it's been around for awhile). Speed of upload was OK, with images appearing after a few moments. Mobileme is no available & iCloud is not listed (old packaging & software not updated). Also, unable to deal with Nikon NEF (RAW) images correctly (thumbnails only displayed on iPad & low res on iMac?) JPEGs OK. To cap everything, it then flattened my camera battery in less than 2 hours of testing. Disappointed to say the least. Good price for the 8Mb Pro X2 at half its usual price, made me buy it, but the concept just didn't work for me. I'll wait for MKII or another manufacturer.
