Good design breeds great productivity, say the creatives at Behance, who developed The Action Method. That's what sets this pad apart from a regular yellow legal notebook. The visual design reminds you to describe ideas in action steps rather than just jotting them down, in line with Behance's philosophy of "Making Ideas Happen."
Each device has a different form factor, and maintaining consistency takes the stress out of to-do lists and project management. Evernote is a clear winner. You can use it on your desktop or through a smartphone app -- but if you're on a shared computer, you can also sign in through a web browser.
The company has allowed the app to integrate with other tools through IFTTT, further reducing friction.
The built-in chat and real-time editing make Google Docs awesome for collaboration. Even if you're working on your own, it's great to have your documents stored in the cloud and accessible on any web-enabled device. Auto-save ensures that the most recently updated version of a document is always available.
Text docs are most popular, but don't forget that you can create a form and embed it on any site -- which is wonderful for getting feedback from users. The spreadsheet doc is great for a simple budget or keeping track of employee's contact information.

Despite the fancy social networks we see released each day, email is still one of the best ways to connect with customers. The sooner you begin collecting email addresses, the better -- and MailChimp's subscription forms are the way to do it.
MailChimp doesn't begin charging til after you hit 2,000 subscribers. Even if you're not sending out regular newsletters, it's helpful to build your list for when it is time for email outreach.

Uber is neither app nor traditional service, but blends the two. It's a car service with the kind of customer care that wouldn't be possible without mobile phones and GPS technology. It attracts high-end customers with sleek cars and is branded as a private driver rather than a cab service.
But, the convenience is what draws most people in. No money is exchanged with drivers because payments (and tip!) are taken care of on Uber's end. Pricing varies with time and distance, and once you've dropped a pin to request a car, phone notifications let you know how close your driver is. So even if you're standing in the rain, you don't feel totally left out in the cold.
Of all gadgets, the iPad is probably the most ubiquitous. It sort of works as a laptop replacement (but not if you do a lot of coding or design) and is also great for reading blogs or watching videos. Best of all, it's slim, which makes it a great companion for travel or conference-going.
Depending on your use case, there are plenty of accessories, like keyboards or a stylus, that make the iPad work better for you. Not to mention, most entrepreneurs make a habit of staying on top of the latest tech product releases -- and many these days are first released as an iPad app, so it helps to be able to experience these products first-hand.
