I need a hdd to backup my notebook. I would like to go cord free, so the Time capsule is certainly a great match for me. However, Im a little sad it costs so much. The 2TB is $300 My macbook is 64GB storage, and I use around 25GB. I dont need all that extra space. A cheaper with less GB option would fit better. Is there another product similar to Time Capsule? theres gotta be at least 1 product on the windows side, they copy everything.
