What tech products or categories are you most passionate about?

Everything that remotely falls under the umbrella of technology gets me excited, but I've been directing my attention more towards the day-to-day computing devices like laptops, desktops, and smartphones that are shaping the future.

How long have you been interested in technology?

I may have started covering the technology space "officially" in 2016, but I've been obsessed with technology and gadgets for as long as I can remember. I was lucky enough to get my hands on a Motorola Razr V3 in 2006, shortly after which I started writing about technology on my blog.

What was your first computer?

I've been dabbling with computing devices for as long as I can remember, but it wasn't until 2010 that I built my first computer. It coincided with the launch of Intel's 2010 Core processor family, and I vividly remember how excited I was to finish the build and install a copy of GTA IV. The good old days when choosing the right component or finding a stable game to run wasn't a chore.

OPPO has introduced a range of truly wireless earbuds over the years, many of which stand out with exceptional audio quality.

Amazfit T-Rex 2 smartwatch
Amazfit T-Rex 2 Review: Heavy-duty fitness tracking

The Amazfit T-Rex 2 packs a lot of great features and it also promises to offer a long battery life. Is it worth buying? Let's find out.

Amazfit has been able to leave the competition behind with its relatively affordable smartwatches and the promise of great battery life. The company's T-Rex 2 smartwatch-- which I've been using for the better part of the last few weeks -- costs less than $200 and it has lasted me well over two weeks on a single charge. It falls short of the company claims about its battery life, but I'd say it's still quite commendable given my usage was also on the heavier side.

Amazon Echo Sub vs Echo Studio: Which speaker to buy for your home in 2022

Let's take quick look at the Amazon Echo Sub vs Echo Studio comparison to find out which is better to buy for your home audio setup in 2022.

By 

Amazon introduced the Echo Sub in 2018 as a solid option for those who wanted to add a bit more bass to their audio experience. It works with other Echo speakers to help create solid sub-bass that the speakers couldn't produce independently. While it was a solid addition to the Echo-heavy home, it had some frustrating limitations and the audio quality itself wasn't any good compared to other premium speakers out there. So the doors were still open for a bigger and louder Echo speaker, which is why Amazon launched the Echo Studio. It's a more advanced speaker with better sound processing and output.

Samsung's Galaxy Tab S8 series has some of the best Android tablets you can buy in 2022. They can't compete with the best iPads yet as Apple continues to widen the gap with iPadOS 16, but they still set a new standard for premium Android tablets. There aren't too many tablets in the Android space that come close to matching the general performance and user experience of the Galaxy Tab S8. If you're looking for alternatives, then we think Xiaomi's Pad 5 series has some solid options. It may not be easy to get your hands on the Xiaomi Pad 5 Pro / Pro 5G, but if you're looking to buy one or if you're simply wondering how they compare with the Galaxy Tab S8, then you've come to the right place.

The Echo Sub is Amazon's $130 subwoofer that works with other Echo speakers to put out a fairly solid bass. The company released it back in 2018 as a companion product for those who already owned a couple of Echo speakers. If you're shopping for a new speaker, you may be wondering if the Echo Sub is still available to purchase now and if it's worth considering in 2022. It can, after all, add more bass to your existing audio setup for a reasonable price.

It's no secret that the tablet space in 2022 is mostly being dominated by Apple's iPad options. Unless you're specifically searching for an "Android tablet" you're likely to end up on a list recommending you to buy an iPad of some sort. But that's not to say you can't find good Android tablets out there. Samsung's Galaxy Tab S8 lineup is making huge waves in this space right now. In fact, the vanilla Galaxy Tab S8 is the one we recommend for most people out there, even though the Galaxy Tab S8 Ultra is the one that is the most impressive.
