I'm guessing we must've had a terribly different experience with pre-3.0/3.5 editions of D&D. I'm pretty sure that we went through characters like they were Fruit Stripe gum (ie. they'd be gone inside an hour and we'd have to get a new one).
Maybe I'm just strange, but most of the things people are nostalgic about are the things I disliked the most about previous editions of D&D.
Heck, the only thing I miss about older editions is... umm... sorry, can't think of anything. Hated the art, hated the demihuman level limit stuff, hated the whole "I'm the DM so the rules don't apply to my NPCs/Monsters" thing (I'm a huge proponent of the 'if a rule applies to the PCs, it applies to the NPCs as well' theory*), hated hobbity halflings (the kender-like-but-not-so-annoying / slightly-gypsy-like halflings of 3e are far more enjoyable to me), hated dual classing/wonky multi-classing rules, hated the multitude of tables everywhere, hated facing, hated THAC0, and hated gygaxian dungeons.
* I'm a firm believer in the idea that it takes a more skilled person to write a story and find out how to make it work within the rules than to just hand-wave it and claim Rule 0. If you can't find a way to make it work, then keep looking.

To the people who complain about 3.x stat blocks being huge, I have posted below the stat block for a 10th level fighter.
Bob Zjerunkul (Human Fighter 10)
S 16 D 12 Co 14 I 8 W 14 Ch 10
HP 76 AC 23[FF 22/T 12] Init +5
Melee +2 Longsword (+17/+12/+7, 1d8+7), Ranged +2 Light Crossbow (+14/+9+4, 1d10)
Fort +13 Ref +8 Will +9
Feats: Power Attack, [Great] Cleave, (WF, WS, GWF) Longsword, Imp. Toughness, Great Fort., Lightning Ref., Iron Will, Imp. Initiative, Rapid Reload.
Skills: Intimidate +13, Craft (Armorsmith) +12
Equipment: +2 Longsword, +2 Heavy Crossbow, +1 Fullplate, +1 Heavy Shield, Cloak of Resistance +2, (random other crap).
Sure, it's bigger than the average 1st Ed stat block, but it only took me 5 minutes and it'll fit on an index card.
