Other than your smartphone, what piece of hardware is a must-have for entrepreneurs?

1. Multiple monitors: We work with multiple monitors – usually our laptops plus a PC. When you work online, there’s no other way to efficiently bounce between dozens of web pages and files. I usually have two or three screens available in addition to my laptop. What it takes up in pure physical space, it makes up in saved time and patience. Plus, it makes me feel like an awesome, futuristic computer hacker!” -Manpreet Singh, Seva Call.

2. Old-school phone: Nothing is more frustrating than trying to have a conversation with someone who is using Google Voice and a cell phone in lieu of a landline. If you’re running a business, you need a landline phone. Period. Shell out the $15 or $20 per month, and save yourself (and your customers) endless frustration. -Brittany Hodak, ZinePak.

3. Extra battery: If every piece of hardware were a Greek hero, the iPhone would surely be Achilles. This is because it’s a mighty business tool with a fatal flaw: the unreliable battery life. Never leave home without an extra battery. You can find hundreds of iPhone batteries on Amazon.
