Lately I bought the Twelve South BookBook, TS-12-1319, Travel Journal Vintage Brown .
This is a great looking product. A leather covered case to store your power cord, headphone and other travel accessories.
The Wireless Magic Trackpad
and the Apple USB Superdrive
fit tightly, an Apple Wireless Keyboard MC184LL/B
doesn't fit. But the basics does fit very well.
It has a soft pocket for an iPad of any size. Some straps to hold the stuff in place. And small net pockets to hold the smaller items like dongles, USB keys, and SD cards. A pocket the size of and iPod or iPhone (I don't think that the bigger iPhone 6 fits).
With all those pockets and straps the case is versatile enough to hold almost anything.
So if you like leather and book like cases, this product is for you. Good looking and big enough for the basic accessories that you need to carry. It better then to just drop them in a bag.
If TwelveSouth, or any other company wants an idea, make that BookBook 0ne (1) centimetre wider, sometimes we need to play Tetris with the accessories to make them fit well.
