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. That a Netflix app in your pocket or are you just happy to stream me?
Netflix (Nasdaq: NFLX) updated its App Store application yesterday, now allowing iPhone and web-backed iPod touch devices to get in on the same streaming fun as the iPad.

It rocks.

Sure, it's smaller. I almost had to squint when I had to read subtitles yesterday on a foreign flick I was watching. However, it's truly portable, and the iPhone version even works on 3G when Wi-Fi connectivity isn't available.

Netflix has gone from making its digital service attractive for millions of iPad owners to making it the "must have" subscription for tens of millions of iPhone and iPod touch owners.

2. It's not grotesque if it's Grouponesque
Shares of Travelzoo (Nasdaq: TZOO) popped 6% higher yesterday, after the travel deals publisher announced the rollout of Local Deals. Travelzoo is taking a page out of Groupon's playbook, selling vouchers to discounted local experiences.

It's easy to see why companies are drumming up models that ape the success of heady upstarts including Groupon, Living Social, and BuyWithMe.com. A recent round of financing earlier this year pegged market leader Groupon with a $1.2 billion valuation. Travelzoo's market cap clocks in just shy of $300 million.

Travelzoo has a shot here. It already has 21 million opt-in recipients of its weekly "Top 20" emails with 20 sponsored and vetted travel-related specials. In other words, it already reaches the thrifty deal seekers. Now it just needs to target its expanded promotions locally.

Everyone seems to be hopping on this bandwagon. Restaurant reservations specialist OpenTable (Nasdaq: OPEN) was upgraded by Merrill Lynch this week, largely on the promise of its Groupon-esque Spotlight feature. Yelp announced its entry into this niche yesterday.

There may be a shakeout when this industry gets too crowded, but for now Travelzoo is in a compelling targeting position.

3. Let's grab a knockoff Tiffany handbag in Chinatown
Tiffany (NYSE: TIF) is thinking outside the jewelry box. The high-end jeweler is rolling out a line of designer handbags, hoping that its luxury brand is portable, literally.

I like this move. The pricey bags won't hit stores until next Wednesday, but it's easy to see the Tiffany holding its own against the entrenched Louis Vuitton, Coach, and Chanel handbags of choice.

Tiffany's name epitomizes class, and it's the only luxury jeweler that could probably succeed this product-line-widening move.

4. Turning landlines into buggy whips
In a gutsy move, Google (Nasdaq: GOOG) is offering Gmail users the ability to call landline and cell phones right from their computers. In a promotional initiative that harkens back to Skype's early days, calls placed to phones in the United States and Canada will be free through the end of the year. International calling is available at attractive rates.

Google has been gradually building up to this, ever since it acquired Grand Central and rebranding it as Google Voice. However, Google's timing is especially keen here as it pulls the rug under Skype's IPO filing.

5. Kindle wax
Amazon.com (Nasdaq: AMZN) is still tightlipped about the actual number of Kindle readers that it's selling, but at least the sales pace is improving.

Amazon announced that it has sold more Kindle readers during its latest model's first four weeks of availability than any previous incarnation.

Sure, Amazon is pricing these puppies aggressively. Whether bibliophiles go for the $189 3G model or the $139 version that requires Wi-Fi for downloads, this is a far cry from the original model that rolled out at $399 less than three years ago.

Amazon is basing this personal best on the number of units sold this month, so a cynic can always argue that the math on net sales might not be so kind given today's cutthroat pricing. However, this is still comforting to see after Apple's (Nasdaq: AAPL) iPad seemed to steal the show after its springtime launch.

The Kindle's for real -- as long as Amazon's margins hold up this quarter.
