I'm planning to expand my wireless network, so I'm deciding whether I should purchase another AEBS or a Time Capsule. I've never had a TC before because I hear so much horror stories about unrecoverable data after it dies. Do you know if Apple has improve the quality of it lately so that it lasts longer? Should I buy it? Or do you recommend me to get an AEBS and get an external harddrive to do my backup manually?
