I have been using bamboo before, but switched to Intuos 4 in January. In fact, I really miss bamboo. I like the touch screen because the shortcut keys are at the top, so I can only use my right hand to draw and press shortcut keys, and my left hand can be lazy. The shortcut keys of Intuos 4 are on the left side, which I am not very used to. But it seems that most people like the shortcut keys on the left? Maybe it’s because I’m used to bamboo. But Intuos 4 has many more shortcut keys than Bamboo, and the pulley can switch between 4 types. Intuos 4, except the S model, has two small LCD screens, but the Bamboo does not. The advantage of that screen is that it shows what function you set the shortcut keys to. When I first started using bamboo, I always forgot what the shortcut keys were.
The pressure sensitivity level of Bamboo is only 512, but I don’t think that has much impact. Personally, I think that if you are not a particularly professional painter, 512 levels of pressure sensitivity will be fine. Intuos 4 is rated at 2048, but the default is 1024. The one I'm driving now is 1024. The effect of pressure sensitivity on painting is that you are more sensitive to the force of your hands. The poster said that the effect of the marker pen can be achieved on any board. It depends on whether the software you use has the marker pen function. That tilt angle can be used if the poster is a calligraphy enthusiast, but I actually don’t think it is very useful. However, bamboo has a problem, that is, the pressure sensitivity often disappears, and the USB needs to be unplugged and replugged, and sometimes the driver must be reinstalled. I only encountered this problem once with Intuos 4.
Then the board surface of Bamboo is slipperier than that of Intuos 4, but with a piece of paper on it, it becomes the same. The board of my bamboo is white, which seems to get dirty easily. I've always stuffed the board into the foam bag that came with it when I bought it, so it's fine, but my data cable is...
Then, is the poster's monitor widescreen or regular? The boards of these two models are both wide, but the Intuos 4 can adjust the drawing area so that the drawing area is consistent with the aspect ratio of the monitor that is not widescreen, but the Bamboo cannot. My screen is a regular screen, so when I first started using Bamboo, I was not used to it. It felt like all the straight lines I drew were curved. There is also "fine drawing", which means you can draw on the board as large an area as your monitor. Bamboo doesn't have it, but I don't think it's used much.
The above is the difference I feel so far. After all, I only bought Intuos 4 in January and I haven’t done much painting.
