I just received an Indigo with 512 GB SSD and configured it with no issues. I am looking at it as the 'coffee table' machine. I have 16" M1 Max MBPro and a 14" M4 MBPro, along with an M4 Pro Mac Mini as my desktop machine. This machine may make the 14" MBPro redundant but we will see. At $700 all in, it is worth having one to play with and keeping around unless it is just not usable.
First impressions are very good. High quality fit and finish with the definite feel of a high quality Apple product. Setup was easy, although I thought the process a little slow at times. This may have been just the time of day and Apple's slow authorization of my iDs etc.
Keyboard: Nice but a little clicky when compared to the MBPros and not quite as smooth feeling. It feels like the Magic Keyboard supplied with the 24" iMac which is also a little 'clicky'.
Trackpad: Works just as well as the haptic track pads and I would be hard pressed to notice the mechanical operation.
Magsafe: This an irritation as we have MagSafe charging cables around the house to plug in the MBPros (my wife also has a 16" M1 Pro MBPro) when needed, so we need to make available a conventional USB C charging cable, which is a step backward. First world problems I know, but a conventional cable is just a little less convenient.
Backlight for keyboard: Probably the thing I miss the most, surprisingly, as I had not expected this to be an issue. I am getting used to it as I am a touch typist but it is more noticeable than expected and possibly the biggest issue I have.
Screen: The default wallpapers do not do the screen any favors as they are over bright and tend make the screen look as if it is blooming and slightly fuzzy. Restoring my default wallpapers did the trick and the screen looks excellent and is perfectly nice for normal use.
Battery Life: Excellent. After 6 hours of use, setting up and playing with various apps, the battery has dropped to 97% from 100%.
Ports: Inconveniently both on the left. It would be nice to have had one on the left and the other on the right (especially for charging). I used the slow speed port for charging and connected a hub on the high speed port which had an SD card slot, some ports. I connected an ACASIS 2TB TB4/USB drive and got around 975 MB/s (read and write) which was decent enough (this compares with the internal SSD which has 1.5 GB/s read and write transfer speed) and in line with the port's 10Gb/s specification.
Performance: Works fine on all my normal web browsing, email and document activities. I have not done any really heavy duty photo processing which I will try later but reviewing and doing some minor tweaks on some new photos I took was easy (I take RAW and edit them for distributions in my library). I loaded 10,000 tracks from my Music library and have been streaming them with no issues. The machine feels fast and responsive with no issues encountered due to RAM pressure. I am not expecting this machine to be used with Lightroom or DxO Photolab or FCP or DaVinci Resolve. I have other machines to do that heavy lifting. This is a machine which I can pick up, do my emails, edit documents, browse the web, review pictures and play music. For that purpose this machine is ideal.
Summary: This is a delightful machine that looks superb in Indigo and feels easy and fast enough for general use. And for $700 it is an absolute bargain.
