The Wacom Intuos tablet and stylus
There are various model and sizes of Wacom tablets. I use a Wacom Intuos CTL-6100WLK-N 8" tablet, which connects to my Mac Book either by a USB cable or by Bluetooth. The tablet is charged up using the cable and, once charged, can be used without the cable. The tablet is the medium size of the range. The stylus is fitted with replaceable tips which will wear down with use, and have to be changed before they get too small to extract with tweezers! The stylus comes with refills inside the base, and packs of 5 or 10 can be purchased online from suppliers like Amazon or eBay. For the beginner, it may take a little time to stop looking at the pen hand and concentrate on the screen cursor - but it soon becomes second nature.
