Hipmunk , the site that takes the pain out of finding your next flight, has raised a $1 million angel round from the likes of Ashton Kutcher, FriendFeed creator Paul Buchheit, WordPress (and Automattic) Founder Matt Mullenweg and several others, including “super angel” Ron Conway’s SV Angel.

Most flight search sites haven’t changed in years. They have an intimidating search page and endless pages of flight results. Finding the right flight often takes all afternoon—or all week. Himmunk is here to change that.

It’s refreshing to find a web app that solves a legitimate, common consumer problem. We see a lot of social communication tools focused on web geeks and early adopters, but not as many that are focused on solving the everyday problems that the average person experiences.

Hipmunk effectively solves the problem of sorting through half a dozen slow and painful discount travel user interfaces to find the one flight you need. According to the company, “Hipmunk makes intelligent decisions about which flights to show you. For example, if there’s a cheap, non-stop flight on your favorite airline, Hipmunk will hide more expensive one-stop options on other airlines.”

Following its debut at Target stores this weekend, Apple’s iPad also became available for purchase from Amazon’s online electronics department on Monday — the first online retailer to carry the device besides Apple itself.

It may seem odd that Amazon would carry a product (albeit through a third-party retailer) often referred to as the “Kindle killer” in its store — especially after disparaging said product in a recent slew of TV ads — but financially it makes a good deal of sense.

Not only is Amazon poised to profit directly from sales of the highly popular device, but also from sales of its e-books via the Kindle app for iPad. Since the Kindle app is arguably superior in both functionality and inventory compared to Apple’s iBooks app, each iPad sale presents a new opportunity for Amazon to expand its e-books business as well.

After all, Amazon’s e-books strategy hinges on selling actual e-books rather than selling e-readers; consequently, the company has worked hard to brings its Kindle app to as many platforms as possible, including Mac, PC, iOS, Android, BlackBerry, and, most recently, the web.

Amazon is carrying all six models of the device: Wi-Fi-only 16GB, 32GB and 64GB models, as well as Wi-Fi and 3G-enabled 16GB, 32GB and 64GB models.
