SAN FRANCISCO - I stopped by the Rain Design booth at Macworld/iWorld. The company makes a lot of great looking Mac and iOS device accessories, but the iSlider really caught my eye. This is a cool iPad stand that folds up into a self contained box that fits in your pocket. To use it, you slide a tray out of the case. This is clever, because the stand then has a base that's long enough to really support your iPad. It features multiple viewing and typing angles, and it's has a great look and feel. In addition to the photo below from the show floor, there's an animated GIF that shows the device being unfolded. Rain Design introduced this last year, but it's shipping now for US$49.90. If you stop by Booth #642, you can get it for 20 percent off.
