A good choice,
Amazon Verified Purchase(What is this?)
This review is from: Wacom Intuos4 PTK-540-WL Wireless Tablet (Electronics)
Bought this over the Intuos5 as it was much cheaper and has displays. Feature wise it's the same as the newer models except doesn't have touch function (which isn't of any use for me anyway). The size of the usable surface is smaller because this is the wireless version but the difference is negligible.
The surface itself became smooth before I had the need to change the first nib.
The tablet works fine on Mac OS Lion and Windows 8.1. The software crashes sometimes on Windows 7 but is quickly fixable by reloading the settings.
My only complaint is that the palm rest is a bit squeaky.
