Fiber Optic Internet
Thanks to Verizon and AT&T bringing fiber optic internet to the average consumer household, even Americans can have lightening fast download speeds like the Scandinavians!
Touch screens
This was definitely the decade of the touch screens. Think of the Nintendo DS, the iPhone, the touch screen PC, and multi-touch touchpads on our own laptops.
Internet Anywhere
You can have Internet in your pocket, in your car, on a bus, in a plane, on a boat, on a mountain, by the sea, in a train. Yeah, Internet everywhere is pretty much everywhere.
Apple Airport
Apple didn't invent Wi-Fi, but like USB before it, Apple lead the industry to the new wireless networking. All you need is an Airport base station and an Airport card in your machine and you're golden. 
HDMI
Okay, we'll admit that HDMI has some quirky issues, but it's one cable to rule them all. Instead of having up to five individual ports to plug stuff into to get sound and video, one cable does it all. 
Solid State Drives
Finally, a piece of hardware that didn't fall apart when you carried your laptop around wrong side up. Though they're still a bit pricey, SSDs have become second choice in the computer world today, and without their inception, we wouldn't have a way to keep our laptops moving with us without completely ruining our treasure trove of data--the drive. 
Online Shopping
Next to online banking, shopping for everything and anything online has become one of our biggest vices in the past few years. Groceries, used books, antiques, and medications can all be purchased online from various retailers. The ability to simply buy something with a few clicks of a mouse button makes it difficult to avoid impulse purchases, and may be the reason some of us here at Mac|Life headquarters aren't saving as much as we hoped to this holiday season.
Bluetooth
If you've got a tendency to get completely turned on by the idea of wireless computing, than Bluetooth probably warmed up your socks this last decade. This seamless technology helps us sync up our mobile phones with our computers, and our cars, and we can't imagine a world where Bluetooth syncing isn't available. 
Photo Tagging
The fact that digital photos made a big play this decade wasn't enough. Facebook and various social networking sites implemented photo tagging so that everyone around the world wide web would know who was doing what and when. Though this kind of photo tagging has had in benefits in cases where, say, you needed an alibi, it can get annoying when that poorly taken photo of you surfaces the web. 
Open Source
Oh, open source and it's enchanting ways have been around for decades. However, these last few years have shown an ever-increasing interest in the idea of free software for all and will definitely set the pace for how the software and Internet giants attempt to knock each other out of the ring. 
Apps and the App Store
With a ton of applications, it's no wonder that businesses everywhere are scurrying to follow Apple in the App store trend. Android already had a pretty well established marketplace, and big time competitors like RIM and Palm aren't far behind.
Pixar animation
Pixar’s first film came out 15 years ago, but their constant technological innovation, and emphasis on evocative storytelling continues to push the envelope for movies and other forms of digital entertainment. And their CGI animation style holds up remarkably well, compared to other movie special effects.
Photoshop
Yes, Photoshop hit the stores way before we even knew we would outlast Y2K. However, there’s something to say for Adobe’s most versatile graphics editing program, as it’s undergone several incarnations since the turn of the decade, including 5, 7, and rebranded CS, which stands for Creative Suite.
