A thought occured to me last night that one of the major problems of the psion is that it doesn't really have a niche. When they first designed 3e (and even further back for AD&D and OD&D), they probably thought up a list of possible supernatural effects and split them up between clerics and wizards (with a bit of overlap). Then they added the psion, which basically had to do the same things the cleric and wizard already did - OK, sometimes the psion is better at something, but there are very few things that are exclusively psion-ish.
One possible solution to making the psion more attractive might be to decrease the portfolio of powers available to wizards and clerics instead of increasing the power level of the psion (OK, it could probably use a bit of boost anyway). Some spells that should probably leave the wizard list would be things like Detect Thoughts and maybe various Charm/Dominate spells - or at least increase their level.
The major problem I can see is that removing most of the classical psychic abilities from the wizard would totally nerf the Enchanter and to a lesser extent the diviner (ESP and telepathy/mind control are the first things that come to mind when talking about psychic powers, with telekinesis a distant third).
