Small USB Secondary Display for your Notebook
Let me show you the latest gadget I got from Bic Camera at Yurakucho.

Its a small 7 inch external LCD display on the left. You can use it on a Mac or a Windows notebook.

It connects to your computer via an USB cable. You don’t need external power. This makes it compact and portable.

There is a little stand at the back that can be swiveled to position the display vertically or horizontally. Its made by IO-data and I have not seen this product outside Japan.

Its useful in situation such as one in this image where I am editing a video on my notebook display and monitoring YouTube upload on the secondary. I also use the secondary display for my Skype and other IM windows. It might also come in handy for netbook users.
On my macbook, it works great even when I am connected to the projector. I can mirror my Macbook screen and the projector screen. The secondary display, I use as a secret window to keep my browsers with search, skype, twitters etc. that I don’t want the audience to see.
It costs about 14,000 Yen or around 145 USD.

It looks very pretty! I've been looking at these DisplayLink USB powered monitors but I didn't realize Japan had so many. Looking at your model sticker, I googled for "usb7xw" and found a retro looking one by Buffalo Technology. Over here in the States, only the 8" and 10" Samsung ones are available. How does the display feel now that you've owned it for a week? Is it practical?
I like it Kevin, perfect for skype and gmail. I wish though it was 8\” or 9\” but I think that would hit the battery harder too. It's small enough to carry in the bag. I heard about Samsing too, and heard that they could also double as picture frames.
