Specification-wise, Wacom's Graphire Bluetooth CTE-630BT is akin to its wired Graphire 4 range. With similar sensitivity and resolution levels, the performance of the Bluetooth version is comparable with that of the CTE-640, the flagship of the Graphire 4 series. Nevertheless, the CTE-630BT delivers an entirely different experience, based largely on its wireless status.
Physically, the tablet is quite well designed. It's thin, lightweight, with a simplistic and convenient button arrangement. A large, 200mm x 150mm active area sits in the centre, surrounded by an adequately wide bezel. There wasn't enough room for our hands when trying to fill in details on the far edges of the active area, but on the whole, the balance between size and comfort seems to have been well optimised. A clip on the top edge provides a resting place for the stylus; a little inconvenient when the tablet is sitting on a desk, but fine when carrying it around.
The freedom of movement when using this tablet is really enjoyable. Without the restriction of cables, you can move around while using the tablet or even just simply sit back with it resting easily in the lap. However, the wireless technology applications go further. Imagine a teacher being able to walk around a classroom, writing onto a projected 'blackboard'. The same technology could easily be used in business presentations, allowing for diagrams and images to be created in real-time, easily and on-the-fly. The breadth of possibilities opened up by unshackling the tablet from its cabling really adds to its tablet's versatility, in a way that beefed up specifications and pressure levels just can't. This is not to say that the tablet's performance is lacking in any way, only that it distinguishes itself in other areas. The specifications are not at a professional level, but they still are high calibre. With 512 levels of pressure sensitivity and 2032 lines per inch of resolution, we got impressive results, creating detailed and precise drawings. Response times are reasonable, although there is a slight lag, only a few hundred milliseconds at most. One of the best facets of the tablet, however, is the strength of its signal. In an office jam packed with almost every wireless and Bluetooth device available, we still got a strong, clear signal through multiple doors - it took a very thick, concrete wall before the tablet dropped out completely.
Conclusion: Professionals and casual home users probably won't get the most from this tablet, but those with a keen eye on its wireless applications will find it a powerful tool.
