My Mac history as a point of reference:
MacBook 13" 4,1 (2.4 GHz C2D) 2008-2012
MacBook Pro 15" (2.2 GHz i7) 9,1 2012-2019
iMac 27" 19,1 (3.0 GHz i5) 2019-Present
MacBook Air 9,1 (1.1 GHz i3) 2020-Present
I have the base silver MacBook Air, meaning it has the i3 CPU, the 8GB of RAM, and the 256 SSD. I have had it since Monday.
Things I like about it:
The construction, rigid, solid, well put together, etc. You know what I mean, Anything build quality/design wise Apple got perfectly right. No faults whatsoever.
I like the screen, I think it is actually phenomenal for what it is. I run the computer with the screen resolution set to emulate my old MBPs screen display area size, looks like 1680x1050 (retina up specced). I think that this is great for me to read PDF files full where two 8.5x11 formatted pages are displayed side-by-side. I'm doing this a ton these days. The resolution provided by the Retina display is fantastic for this, it's really as good as it being printed out, except for that it's backlit, unlike paper not on a light table (who actually has those? (irrelevant comment)). It's plenty bright, and seems to be color accurate enough for most purposes, a bit off my iMac's screen, but neither are calibrated... Who the heck would want a touchscreen on a PC laptop when you can have the stellar display quality of this MBA?
The size/weight: obviously way better than the 15" MBP, good for bringing to work so I can read those PDFs so I can study on my lunch break for my Med Lab certification.
Battery life: great, as expected. Nothing more to say beyond that, except that it seems like it lives up to Apple' stated expectations. Also: charges quickly with 30W power adapter.
Trackpad: I like the size, and overall quality: everything everyone has ever praised about the trackpad, I still agree.
The keyboard: I was hesitant about it, I still prefer the classic MBP's keyboard, still found on the [WIRED (now discontinued)] Apple 110 key keyboard. I purchased the 110 key keyboard in 2016, and to me that one is better than the wireless Magic Keyboard that came with the iMac or this MacBook Air's keyboard, or the even worse butterfly keyboard I have only ever used at stores on display models. Overall ranking for typing feel and sound: 1st place: 110 key apple brand wired and 2012 MBP, 2nd place: this MacBook Air's keyboard slightly edges out the equivalent 2019 iMac included wireless Magic keyboard (3rd), 4th and last place is the butterfly style. Also, Il like that it has the function keys, and this is the first time I've had a fingerprint sensor on a Mac, and I like it's implementation.
CPU speed is fine, it pulls up anything I want quickly enough. Any heavy duty stuff will be done on my 6-core iMac.
The RAM and SSD are fast and large enough for me here, 8GB and 256 GB doesn't seem limiting for a second computer. 40GB RAM and 1TB HDD are good for a desktop. Having an SSD made me learn something, people who say your a fool if you get a hard disk drive in this day and age are fools themselves. The slowness attributable to a spinning platter isn't actually horrible like claimed.So what if something takes a bit longer to open up or seek something out, not everyone needs perfectly instant access to random things on their hard drive or a bajillion Gb/s throughput.
Things I don't like:
The integrated GPU struggles with things I wouldn't have expected it to struggle with. Worried what it would be like if I ever connected it to an external display (unlikely with me having 27" iMac).
The CPU while the laptop never feels warm to the touch, kicks on its fans at the exact moment you ever do anything half difficult with it. With the 2008 MacBook, the 2012 MBP, and the 2019 iMac, it took a while for concerted CPU effort to get the fans going. Not so with this one. Temps are very peaky, heats up and cools down in no time flat. This worries me more than anything, because I fear those sudden temp swings up and down may shorten the life of the CPU (solder connections, etc.) Also, fwiw, I have gotten past indexing and photoanalysis, et cetera. However, the fans are quiet, similar to the iMac's, not like the old MB or MBP which were ready to make those laptops take flight. Handbrake or Cinebench or whatever full bore would take at least two minutes to get above even HALF the fan's max speed. Here with the MBA, open Google Earth Pro (my favorite application) or Stellarium, or anything else that computes things, and it's ready to go. This all leads me to think that the CPU is physically small/light weight. Computationally, it's fine for what a MBA is for, I just wish it could be literally heavier to take longer to heat up. Whatever. I'm probably overblowing this, but it is what I think. The iMac's CPU is literally 2.8x larger and is rated/cooled for at least 6-10x more watts and it shows.
I wish it had a USB A port, but having AirDrop and a dual usbc/usba jump drive makes this less difficult. Honestly, for me as someone who is pretty much just doing (for now) pdf document reading, YouTube video watching, music/podcast listening, I think it's overall fine.
If Apple had quicker shipping I would have gotten the i5 quad core upgrade for the $999 mil/edu discount through Apple rather than the $950 i3 through Costco with their 1 extra year extended warranty.
Overall for a college student like environment, it's good, I was honestly considering everything from the basic $350 iPad, to the iPad Air, to the iPad Pro, to this, but ultimately having a desktop type Mac OS is worth $600 alone over anything iPad OS wise. iOS stinks to high heaven for me when it comes to multitasking. I hate hate hate hate hate it.
P.S. MESSAGE TO APPLE, BRING BACK DASHBOARD!!! Dashboard is one of the best thing's you have ever done software wise bar none, and I'm oh so glad I've refused to downgrade from Mojave to Catalina on my iMac.
