How cheap is storage these days? Price watchers in Japan report that the retail price of a 1TB internal hard drive has marched relentlessly downward, breaking JPY20,000 around March, and dropping to around JPY12,000 currently. Some retailers are blowing out name-brand 1TB drives for as little as JPY9800; check low-price shops like T-ZONE or TSUKUMO for bargains.

It won't be long before talk of "deleting stuff to make room on the hard drive" becomes a delightfully quaint thing of the past.
