Another effect is, that it makes spontaneous casters obsolete, pretty much, when you use the UA system. You could, of course, have prepared casters hash out their prepared spells with all spell points applied in the morning (which would kinda negate the whole point of using it, because it will surely not be simpler than the vancian system then, and will eat up A LOT of time for preparation).
I believe a level 5 druid with 20sp would think otherwise. In the original system, he could cast 3 CLW, 2 Flam.Sphere, and 1 Call Lightning, or just 6 CLW, while with spell points he could memorize 10 CLW and 2 Call Lightning, or just 4 Call Lightning, or even 20 CLW! I agree that it doesn´t get any simpler when you use sp and memorization by the time you get to 10th level, but it still beats vancian slots if you ask me
But most of this discussion revolves around what do you think caster actually do. I believe that wizards, clerics, druids, etc study tomes and books, brew potions, learn secret languages, mix ingredients, pray to gods, sacrifice virgins, etc to infuse themselves with a magical ability, and that´s why they have to 'memorize' spells - wich in my concept is actually preparing the spell to be cast later. Sorcerers and bards dont need that, they are magical beings themselves ('Sentinel detected Mutant Life Signals' kinda magical

).
To me, wizards spend material components while preparing their spells, and for simplicity, dont loose them after casting, they only need to rest in order to recharge them (so I wont ask players what spells they want to prepare for every single day

). On the other hand, spontaneous casters like sorcerers and bards start with Eschew Materials, because magic is natural to them.
My personal problem with spell slots is that, when you cast all your 2 fireballs, you cant cast another, even though you have 20 levitate and 47 knock memorized. Even if you´re a sorcerer, it´s ridiculous having to say "i dont have the power to knock another door, i'm all used up", and then cast dimension door
I like spell points, but the way they are presented in UA makes wizards too good to be true. Having them prepare their pool of spellpoints seems ideal to my view of things. So I will use that, not because it's simpler, but because it's ideal.
