Anyone use them? I have my eye on the Eye-Fi 4GB Connect X2. Curious as to whether it does what it says on the box..to a high degree I suppose. So if I'm not mistaken, it can connect via wifi to my home PC if it's on, or to an ipad/iphone/smartphone using its own wireless network, or upload to websites like flickr. I was thinking it could be useful when going on vacation; I'd love to have the option to backup my pictures while away. Unfortunately, I don't have the flickr paid account and would be limited to 200 photos. Also, I don't think flickr even saves it at full size jpegs. Anyone use it with picasa or the other supported sites? I'm also curious as to whether or not you can send it to multiple locations..aka a tablet device, your home ftp server, and flickr for example or if it can only transfer to one destination. Thoughts and experiences would be appreciated.
