I am thinking of trading in my MacBook Pro for a MacBook Air M3. May i have your thoughts on this. I only use for writing and internet browsing....

I agree with what others here have already said.

• Your uses aren't all that demanding on the Mac's CPU or graphics interface.
• The above being said, be wary of the "base" models that have only 8GB RAM. It's way too easy to run low on RAM, especially if you have several documents, web browser pages, etc. opened at the same time. Most of us here recommend 16GB RAM.
• If you prefer storing files on your Mac's internal storage rather than cloud services like DropBox, OneDrive, etc., then get internal storage of at least 512GB.
• Shop carefully, as often upgraded Macs are available via third party resellers (such as baphotovideo.com).
• Also, look at Apple's refurbished offerings. My experience with them is that, for the most part, they're indistinguishable from brand new, yet come with a significant savings. And the warranty is the same as brand new.
• If by chance you're a veteran, Apple does offer a discount.
• I always recommend adding AppleCare, as I think of it as "insurance". You most likely won't need it, but will be super glad you have it if it IS needed.

Just my $0.02 worth.

Although you did not explain which of the many MacBook Pro models you have, but you will be able to accomplish everything you describe with the M3 MacBook Air.

It is nearly certain it will outperform your existing MacBook Pro, probably by a large margin, but again you need to identify its exact model and configuration for a definitive answer.

the low-end configurations with under 512 MB storage are intended for Students who never store anything on their computers. if you run out of space you can add an external drive.

low-end configurations with less than 16 GB or RAM can be problematic. RAM Memory can't be upgraded, EVER.

The M2 model is not much different in performance, and may save you money.

On your current computer, are you FaceTiming, video conferencing, or watching videos for extended periods? Those raise issues that may affect the choice of keeping your fan-cooled Macbook Pro or getting a fanless Macbook Air.
