I am too in similar situation, while planing my family trip to US I need a good way to backup my photos. I has 2 basic requirements:
- Backup photos without laptop/notebook, as I will not bring one with me (I need that weight for other things)
- It's cost must not exceed 300$
After checking and trying many options I have found a solution that suites my needs. As everyone has smartphone today and most phones has USB OTG support, my idea is to use a card reader connected to my phone via USB cable from one side and portable hard drive with WIFI support (like this one) from another. This way I can use any file manager to copy files from my CF card to a wifi enabled HD. The same HD can be used by IPAD or any other tablet to view those images or other content such movies and/or music, its light, high capacity and cheap.
It not the fastest way indeed, but I don't care if it takes 10 or 40 minutes (I don't know the real numbers yet as I am getting my Seagate Wireless Plus drive in 3 weeks) to backup CF card content.
Hope it helps.
