No you didn't, originally i was hoping to get a 32GB this morning from my local premium reseller, was only 10th in line, but by the time i got to the till they had sold out of 32 & 64GB, and had only 1 16GB WiFi left, so i opted for that, thought i had made a huge mistake, but once i had gotten home and synced some stuff I was ALOT happier with my choice, it depends mainly on how you would use the device, and how much content you have.
For me i have a lot of content but im not going to be using my iPad all the time, certainly not as much as my iPod touch (4th gen 32GB), so its works out fine for me, at the moment I've got 600 songs, 2 movies, 2 TV shows, 20 apps (several of them getting on for 1GB in size) as well as 2 books, and I've still got 1.5GB left, which is perfect for me because im not going to use it as extensively as my touch, but i still have a fair amount of content on it, so overall im quite happy, plus you've saved some money by not buying a larger spec, which is never a bad thing
Bottom line is it all depends on the amount you going to use it, as well as the amount of content that you own.
