Summary: I wouldn't recommend this for professionals looking to upgrade their old Cintiq, but the F350 gets the job done. Out of the box in Ubuntu 10.10, I'm coloring away in GIMP. It takes a little more patience, and the pen acts like a dripping paintbrush, but think of it this way: if you can use this...
Summary: It doesn't really work that well though. I'm using it with Illustrator on an iMac and it's sort of wonky...the sensitivity is funny. Like I said though, it works, it's just very average. You could probably spend a bit more and get a much better product. But then again it was cheap.
Summary: My G-Pen F350 is also having a problem with constantly clicking if i even just hover the pen over the tablet. It started with the pen seeming just a bit oversensitive, but it has been getting progressively worse and now the constant clicking has made it unusable.
Summary: I purchased this as a gift for my daughter who has become quite talented with sketching and drawing. Computers being more and more ubiquitous, it's only natural to want to draw with them. This was our intent. The pad functions well, but is clearly more integrated for a business environment.
Summary: This is my first tablet and I am very happy with it. It is slim and easy to carry. I have no problem fitting it into my laptop sleeve and carry it all around. I use it mainly for note taking in class, and it works great with OneNote.
