As people below have pointed out, arguable it was crappy. Sure, lacked 3G, lacked apps, but the utter ease of connecting to wifi and flicking through Safari…
…anyways, arguable. What’s inarguable is that the iPhone 4, which came along only 3 years later, was a damned miracle. Beautiful design, Retina screen, something approaching a “real” camera—just remarkable progress in that time.
I’m unsure if Apple is going to be able to pull off that hyperspeed progression this time. The Vision Pro seems to have truly wild capabilities, but for a lot of money and with very little battery life. Are we going to have a big leap in price/performance soon? I dunno.
