The inability to provide gapless playback is, quite simply, totally unacceptable.
I have very eclectic musical tastes. Some albums and recordings have no need for gapless playback, with each song or piece standing alone. A great deal of progressive rock and classical music, for example, is written to segue seamlessly from one track or movement to another, and any playback medium worth its salt should respect this. The move into the final movement of Beethoven's 5th symphony, referenced earlier in this thread, is one of the most glorious moments in all music, and reproduction of such should respect this entirely. There's countless other examples across different genres.
I remember gapless support being a big step forward for a firmware upgrade on Squeezebox devices around 15 years ago, but it's been resolved more slowly on some streaming platforms over the past few years. DTS Play-Fi, used by manufacturers including Arcam and Audiolab, has been one of the slowest to get its act together in this respect whilst BluOS, HEOS and MusicCast have supported it for some time.
CD is, and always has been, capable of gapless playback. I have old Sony and Arcam CD players (Arcam's original Alpha) that have no issues in this regard, and I never had this problem on any CD player, including an Arcam CD73T and CD18. I believe it has been an issue on the Arcam CDS50, and Arcam have had moire than long enough to correct this and ensure it isn't an issue on the new CD5. It's the servo/firmware that is the problem, and products shouldn't be released with the promise that a future firmware update will resolve an issue which shouldn't be there in the first place. Get the product right BEFORE you take customers' money. The basics should be right, out of the box!!
It's something else which makes me glad I now have the system I have. It works flawlessly, and sounds as good as (and in some respects better than) any expensive kit I've owned.
