Prices start at $349, but can go as high as $17,000 for a luxury edition in gold. Apple store employees will show you the range of options, including different watch cases, bands and sizes. Reservations are recommended.
But you won't be able to walk out with a watch. The first orders ship out April 24th and buyers can either have watches sent directly to their homes or arrange to return to a store for pickup. The same applies even after the 24th.
Although Samsung, Motorola, Sony and other companies already have been selling smartwatches, none has been a hit beyond a small group of tech devotees. The market will be watching to see if Apple's device changes the game.
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 grey — the first time there has been a colour 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.
. OR THE NEW ANDROID PHONES
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.
SPEAKING OF STREAMING .
CBS' $6-a-month streaming service, All Access, is now available on Roku — the first streaming TV device for the network. The subscription offers live feeds of CBS stations in some markets, along with a bigger library of on-demand content than what's available for free.
Meanwhile, the Roku 3 player now has a new remote control with a voice search button that customers can use to see what's available across multiple streaming services such as Netflix. Another feature tracks when a movie you're interested in becomes available for streaming or gets a price cut.
LIVE TV ON XBOX
Attention cord-cutters and cord-nevers — you'll be able to watch free live local TV stations like CBS, Fox, NBC and PBS through Microsoft's Xbox One. You'll need an $80 dongle that connects your digital TV antenna to the game console's USB port. Shows will show up in the Xbox's TV guide and be integrated into the console's dual-screen "Snap" mode so users can play games and watch TV at the same time. With the Hauppage WinTV-955Q dongle, gamers can also stream the local feed to a tablet computer and pause live shows. The feature is rolling out now to Xbox One Preview members in the U.S. and Canada, and will be available to all Xbox gamers there over the next few months.
OnLive, which streams high-end video games over an Internet connection (like a Netflix for games), is shutting down April 30 following Sony Corp.'s purchase of "important parts" of the company. The service had promise, but never gained much usage. Sony purchased its rival, Gaikai, in 2012 and lets PlayStation owners stream games either for a monthly flat fee or through individual rentals. Refunds are being offered to those who bought OnLive since Feb. 1.
