But the Apple Watch isn't the only gadget available this week. Here are five other new devices and services targeting your wallet.
Don't forget the Macbook...
Apple's new laptop, simply called MacBook, debuts Friday. It's the company's lightest and thinnest laptop so far, making the ultra-thin MacBook Air appear bulky by comparison. Apple borrowed many design techniques from the iPad, including eliminating the fan.
The new MacBook comes in silver, gold or gray—the first time there has been a color choice since Apple ditched plastic for metal on its laptops. The base model is $1,299. You get double the storage and a faster processor for $1,599.

Samsung's Galaxy S6 phones and the HTC One M9 make their general U.S. debut in retail stores. (Online orders have been accepted for a few weeks). Samsung swapped its plastic back cover for more stylish metal and glass to better compete with the iPhone.
It also improved the camera and software interface. HTC also improved its camera and has added home-screen personalization based on location. Prices vary by carrier. No-contract versions generally start at about $650.
In time for the return of "Game of Thrones" this Sunday, HBO launched its stand-alone streaming service, HBO Now, priced at $15 a month. Initially, it's available only to owners of an Apple TV, iPhone or iPad, or to Cablevision's Internet-access subscribers. HBO Now offers the same content as HBO Go, the companion app to HBO's cable channels.
The difference is you don't need a cable or satellite TV subscription.

You could also pay $15 a month to watch HBO shows online through Dish's Sling TV service. That's on top of Sling TV's $20 monthly fee for nearly two dozen other cable channels, including ESPN and CNN. Sling TV plans to debut HBO no later than Saturday as part of an app upgrade.
