Cameras were pretty common on phones, even with video, and the iPhone couldn’t shoot video for years.
There was no customized Home Screen which had a lot of hand-wringing.
Again, as everyone mentions no apps and that’s huge. Let’s not forget that the backup to apps, websites, weren’t made for mobile yet. Not even apples own website.
When the iPhone first came out it was halfway to a luxury feature phone in terms of ability. Until mobile web and apps became readily available, it wasn’t particularly “smart”.
It was subpar in ways people expected more from (basic phone stuff), and great in new ways (Touch! Web!). That sounds exactly like the reviews for this headset.
