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.

In a perfect world, every smartphone making its way to the market in 2022 -- regardless of the price -- would come with a microSD card slot for expandable storage. With powerful internals that can handle all the demanding applications and cameras that can capture highly detailed photos and videos, it makes perfect sense to support expandable storage, right?

iPhone 14 Pro Max compared to iPhone 13 Pro Max

Love it or hate it, you probably have strong feelings about Apple's Dynamic Island. I have to hand it to Apple for embracing a cutout and turning it into something you're willing to open your wallets for. It's a very "Apple way" of dealing with a problem that most Android phone makers have been ignoring and even hiding for years. It's an expertly executed fusion of hardware and software, albeit with a terrible name and some room to improve.Instead of catching the hype train and placing an order for the new iPhone 14 Pro, I decided to give it a little bit of thought. Would I rather have a dynamic island or stick with a notch on top of the display? Unlike a lot of people around me who I know absolutely love Dynamic Island, I am here to make a case for the notch.Look, Dynamic Island is a cool spin on the cutout and it's probably the best use of engineering and design I've seen in a long time. But that doesn't take away from the fact that it has some glaring issues. Hear me out!

They do, however, come up with some surprise flagship launches once in a while and that's exactly what the Motorola Edge Plus (2022) really is.

The Google Pixel 6a borrows a lot of good features from the Pixel 6 to deliver a compelling package under $500. It doesn't come with all the bells and whistles that you'd expect from a top-tier Android phone in 2022, but it's hard to argue against its value. The Pixel 6a may not be competing with other premium flagships on the market, but there's one device that's looking over its shoulders -- the iPhone 12. This one's a close match-up because they have a lot in common. We also think it's better to pit the Google Pixel 6a against the iPhone SE 3 (2022) and the iPhone 12 and let the Pixel 6/6 Pro handle the iPhone 13 series. We've already seen how the Pixel 6a vs iPhone SE 3 comparison plays out, so let's check out the Google Pixel 6a vs Apple iPhone 12 comparison to find out which one's better to buy in 2022.
