Apple's Time Capsule backup drive, initially announced at Macworld last month, is behind in shipments but will officially hit store shelves on Sunday, February 24th. Although Apple's online store only lists the device as shipping in "February," a Best Buy circular for next week lists the 500GB and 1TB Time Capsules as shipping on February 24th. "Most" Best Buy outlets will have three or four Capsules in stock, the tip says. [updated]
Of note is that the circular also indicates an end date for the current Capsules, scheduled for January 1st, 2009. This may imply that Apple will introduce upgraded Time Capsules in roughly the same timeframe; if this occurs at the next Macworld Expo, the end date would give retailers enough time to clear out remaining inventory.
