I think the DualHead2Go is not a good solution because of the following reasons: - It's bulky. Compared to a USB-to-VGA/DVI adapter. It needs to have its own power supply too. Extra weight to carry. - It's more costly. At $200+. A USB-to-VGA/DVI adapter with resolution up to 1920 x 1080 can be bought for $75. - The resolution is horrible. With their analog edition: 2560x1024 (2x 1280x1024) 1280 x 1024 is coarse, especially for monitors >22" And you need to check on your laptop to make sure the graphic chip onboard would support the VGA resolution of 2560 x 1024 too. With the USB-to-VGA adapter, the graphics processing is done on the adapter. You do tie up one USB port on your laptop.
