If you have followed the lists of accessories we have covered here in the past couple of years, you realize there is almost nothing one can’t do with an iPhone or iPad. The Smart Dot by Tangram is another great accessory that turns your iPhone into a laser pointer. It connects to your iPhone’s 3.5mm audio jack and has a companion app so you can use this for presentations and other purposes.
The Smart Dot is compatible with iPod Touch too. It is very small and does not require any separate battery. This also acts as a stylus for your phone. You can use the Smart Dot to control Apple Keynote and PowerPoint presentations. In order to access the presentation mode, you need to make sure your computer and smartphone are connected to a wireless network. You are going to have to download the companion PC or Mac apps for this too.
Speaking of cool accessories, the Keystone ECO MarineCase is a waterproof case that keeps water from reaching your iPhone. It works in any situation that water may be present. The case not only protects your gadget, it also lets you use your device (watch videos, answer emails, send texts, …). The MarineCase is snow and sand proof as well. It is waterproof up to 20 feet. This seems great for taking video underwater. The MarineCase is compatible with the iPhone 4/ 4S. It will cost you under $40.
