3210 and 3310 were *the* milllennial phones!
"I'm not sure few people under 40 will see what the fuss is about. Millennials don't do voice much anyway, and there isn't much else a 3310 (retro or otherwise) can do well."
On the contrary- yes, they were a long time ago, but you forget that the first "millennials" hit their late teens well over seventeen years ago (#) and that the original Nokia 3210- and then the 3310- were *the* archetypal "first wave millennial" phones.
The 3210 was one of the first phones aimed at- and massively successful with- the younger end of the market- i.e. late teens and young professionals- being both affordable and stylish (for the time) (##), and the 3310 was pretty much a continuation of that.
Of course, this was around the time that texting was becoming popular, and that was probably as important as voice- an early sign from the early millennials that, yes, voice wasn't the be all and end all and an indication of how things would go. But in dismissing the 3210 as only being good at "voice", you forget that- again- the 3210 and 3310 were incredibly popular with those same texting teens and students.
All that said, the alleged revival of the 3310 seems like a lazy attempt to exploit nostalgia. Things have moved on. It just wouldn't fit into today's market in that form as-is, and even if you were to slap on a colour display, it'd still just be a feature phone by today's standards - like the Samsung my tech-disinterested Mum got for a tenner- if it remotely resembled the original. And if it didn't, it's not a 3310, is it?
(#) Assuming we take the most common definition being those born between 1982 and 2000. While I've never seen the term "millennial" explained, I'd always assumed it came from the fact those people would be hitting nominal adulthood- i.e. 18 years or so- at or after the turn of the millennium.
(##) Personally, I always thought the 3210 looked much nicer than the 3310. Also, Wikipedia claims the 3210 sold 160m vs. 126m for the 3310, though I'd have assumed the 3310 would have sold more. I'm surprised that the 3310 seems to get more nostalgia than the 3210 regardless, as it was really just a follow-on from the latter.
