5 top tech gifts for the holidays

(BPT) - The holidays are almost here! It means parties and events, hustle and bustle ... and figuring out what to buy for everyone on your list. Sometimes it's hard to get inspired with great ideas that your nears and dears will love at a price you can afford, right? The good news? Inspiration + savings are covered this year. One of the top gifts of Holiday 2024 is technology, and there are a lot of deals out there right now. Done and done!

Here are 5 ideas for hot tech gifts for everyone on your list.

Smartphones for the family

T-Mobile is running a hot deal right now. Get four new smartphones at T-Mobile - this includes Samsung Galaxy S24 and other eligible devices - and four lines for just $100/month. It doesn't get better than that!

These new Galaxy phones are tech-tastic, too, with features like AI, Circle to Search with Google, which can be used to help solve math problems and translate entire pages of text in a different language, and Note Assist with Galaxy AI, which lets you focus on capturing your notes and then Note Assist will summarize, format and even translate them for you.

High tech spiral notebook for students

We've got to admit, this is pretty cool. The Rocketbook looks (a bit) like a regular spiral, paper notebook. Here's the high tech twist: You can take notes, capture ideas, brainstorm, draw - whatever you do on paper - on the pad, and the Rocketbook digitizes your doodles and saves to the cloud device of your choice. Then you simply wipe the pad clean and it's good to go. Look for Black Friday and Cyber Monday sales at your favorite online retailer.

Wrist-worthy smartwatches for athletes (or those who want to be)

Everyone loves smartwatches (if you're not already tracking your sleep and heart rate, where have you been?) and the Google Pixel Watch 3 (41mm & 45mm) takes it to the next level with features for athletes or anyone who may be setting fitness goals for the coming year. The watch has workout prompts like Real Time Guidance - audio and haptic cues for when to sprint, cool down or maintain pace. It gives you the ability to program your workouts and even monitors your cadence and stride. It also has Offline Maps, with driving navigation, search and maps. Here's the deal of the century: Get it for free at T-Mobile when adding a qualifying watch line.

Cute wireless keyboard for people who are all thumbs

Who else is annoyed by typing email or texts or social posts on a smartphone? The Logitech Multi-Device Wireless Bluetooth Keyboard solves that problem with style! It comes in sweet colors like lavender, it's wireless, it's small and portable, and it works with just about any device. Pop it into your backpack or purse and you'll never have to thumb-out a message again.

Speakers perfect for hosting and giving

Have a music lover in your life or need the perfect hosting gift? T-Mobile has you covered. For a limited time, you can get the JBL Clip 5 for free when you pick up a Harman Kardon Onyx Studio 9. The JBL Clip 5 is an ultra-portable Bluetooth speaker perfect for those on the go and the Onyx Studio 9's sleek design and booming sound will take care of all your holiday hosting needs.
