The affordable Bay Trail-powered convertible was only available in the US with 32 GB or 64 GB of SSD storage and now it finally got a 500 GB hard drive option.

Can you buy the keyboard dock with 500gb hdd for an existing T100?
We have contacted Asus and we are sorry to tell you this, but the dock is not available separately. It was, is and will be sold only together with the tablet. If that changes some day, we will be glad to report the news as soon as possible.
Can you change out the installed keyboard-"dock"-drive? I am toying with getting one of these but I want to tinker with it. Also, any ideal why this HDD keyboard option does not come with 64GB SSD tablet in the US? I found a place in Germany that sells that combo.
