The Virtuoso Touch offers a great hybrid writing experience on the screen or on paper, but its large size proves too bulky for navigation, sketching, or detailed line work.

The third stylus in the "black body, silver clip, silicon-rubber nib" group, Targus' ( Macworld rated 3 out of 5 mice ; $25) falls between the Griffin and Kensington models in both weight and length at 4.5 inches in length, and falls roughly in the middle in weight, as well. Like the Kensington Virtuoso, the Targus also provides a ballpoint pen tip--hence the "2-in-1" in the title--which is easily replaceable.

I found the stylus end of the 2-in-1 adequate for both writing and sketching. It's just heavy enough to provide the right balance for writing without needing to put your palm on the screen; however, its weight may prove taxing if you're trying to write for long periods of time. Likewise, it's easy enough to do line art using the Targus, but I had to grip the stylus close to the nib to achieve any sort of precision.

If you're looking for a device that can navigate, write, sketch, and jot down paper notes, the Targus 2-in-1 is a decent offering. However, unless you're specifically looking for a stylus with a ballpoint pen, you should consider a more specialized model.
