Looking for a good backup solution. However, I already have a Billion 7800N, I am ready to sell it, as i'm eyeing on the Airport Expreme as a replacment. We have two networked computers, one Mac, and one PC, but most are all Apple including APple TV. However, I was wondering weather a Airport Extreme would be a easuer option, than just adding a Time Capsule 2TB to the mix. I'm not really concerned with RAID, and to save money, if needed, i could utilise the USB port on these for external storage.. and have multiple backups anyway. I'll get two drives, one for home use, and the other one i'll take with me when i'm out, also USB flash too. Is ths a good solution? and should I just "add" a Time Capsuale, or replace current wireless router with AIrport extreme, and add 1 or 2TB external HD ?
