If you're feeling good about the market, you're not alone. Take my hand as we go over some of this week's more uplifting headlines.

1. My iPad or yours?
Apple's (Nasdaq: AAPL) iPhone 4 may have hit the market yesterday, but let's talk about the iPad.

Apple announced that it has now sold 3 million of the supersized iPod touch devices in its first 80 days on the market.

When Apple cleared a million iPads in its first month, it was easy to chalk up the phenomenon to early adopters who'll buy anything that Steve Jobs breathes on. When Apple cleared 2 million iPads in two months, it was easy to attribute the milestone to the gadget's introduction in several key international markets. But we're not even done with the third month and we're already at 3 million?

The iPad is the real deal, but you probably didn't need me telling you that. You probably already read about this on your iPad.

2. Set lasers to stun
In a move to beef up its already strong App Store presence, eBay (Nasdaq: EBAY) is snapping up RedLaser. The leading barcode-scanner application is a comparison shopping dream. Point an iPhone camera at any product's barcode, and it immediately spits back a list of the online retailers selling it for less than you were about to pay. It also uses the iPhone's GPS positioning to spit out the closest real-world competitors selling the same item.

RedLaser has been downloaded more than 2 million times, and there were nearly a million active users two months ago.

eBay immediately made it a free app (it was priced at $1.99 before), and it's just a matter of time before it incorporates eBay listings and its Shopping.com retail partners into the comparisons.

3. From SueTube to YouTube
Google's (Nasdaq: GOOG) YouTube has won the first round in its legal battle against Viacom (NYSE: VIA). The court granted YouTube's motion for summary judgment in the case that originally found Viacom seeking as much as $1 billion in damages.

I have never professed to being a legal eagle, but I know that a Viacom victory would have pretty much killed the video-sharing industry by forcing sites to staff editors to screen every upload. The Internet would be as boring as your summertime television set.

This isn't advocating piracy or denying Viacom the rightful ownership of its creative efforts. It's just about common sense and a reasonable amount of copyright policing.

4. Bring on the Martians, pirates, and cars
It may be a small world at Disney (NYSE: DIS), but the company likes its screens big. The family-entertainment giant is teaming up with IMAX (Nasdaq: IMAX) to offer three of its most anticipated theatrical releases of 2011 -- Cars 2, Mars Needs Moms, and Pirates of the Caribbean: On Stranger Tides -- on the IMAX 3-D platform.

This may not come as much of a surprise, given the success of Disney's Alice in Wonderland, Iron Man 2, and Toy Story 3 on IMAX this year. Consumers aren't flinching at paying up for premium cinematic experiences, and IMAX is helping studios, exhibitors, and itself in the process.

With multiplex operators converting traditional screens to IMAX's digital systems, not releasing a likely blockbuster on the supersized format would be like leaving money on the table -- or at least the sticky theater floor.

5. Mr. Softy sends us off
Microsoft (Nasdaq: MSFT) doesn't make too many appearances in this weekly column, so let's admire its presence with a twofer.

On the one hand, Microsoft announced that it had sold 150 million Windows 7 licenses since the launch of its non-Vista operating system. Nice. I'm skeptical about the future, but I'll applaud the present.

On the other hand, the world's leading software company also spruced up its Bing search engine by tacking on a ton of entertainment-oriented content. Bing users will no longer need to leave the site to find licensed song lyrics, casual games, and even song streams.

Making the site sticky may seem to be counterintuitive, given paid search's cash registers that go ka-ching when someone leaves the site via a sponsored lead. However, Bing wants to be all things for all people. This is an ambitious goal, but at least Bing has a little fresh ammo to keep its audience entertained.
