No one is denying that? But 1st gen tends to be significantly worse than next gen.
Learn from the past, 1st gen is for suckers.
To be quite honest, first iPhone was hard to resist from buying it and so was the first iPad (which people "suckers" still use now days) Inevitably the succeeders had to be better. It's just the way things evolve.
I did skip the first iPhone, mostly because I didn't need a phone -- I got the iPod touch instead. But I did get the first iPad, and enjoyed it until the 2nd one came out, whereas people who skipped the first gen had no tablets that year. Or they were using one of the many lame tablet attempts put out by other companies, which were all pretty terrible. So I think if you buy a first gen product knowing that the second gen would likely be much improved, but that having it early is worth it to you even with the not quite perfect experience, then you aren't a sucker.
