I have a early 2008 MBP 15", 2.4GHz, 4GB, 8600M GT 256MB. Not exactly the same as yours, but similar. Launchpad is fine on the MBPs screen.
Have you rebooted the Mac? (Not sleep, but shutdown.) Was this a upgrade of your existing Snow Leopard setup or a clean install? If a clean install, was this a clean install of SL, then upgrade to Lion, or a clean install from a Lion boot DVD or USB drive?

Thanks for your response, Asatoran.
It was an upgrade install of SL over Leopard and then Lion over it as upgrade. I have shut it down several times physically, tried with adapter and without. Clean install of Lion means installing so many applications over it. It will take me a day or two. Honestly, some may not even install correctly again. Painful - if there is no other way I will try it.
I have about 90GB free on the system (200GB original HDD size).
From your reply, I am inclined to think something like an old driver of sorts is lingering around and making life painful ?
Is there anyway I can remove the display driver and reinstall it without reinstalling Lion ?

"Upgrades" always have more potential for issues than a clean install. Maybe it's a holdover from my Windows days, but I always mentally prepare myself for the potential of a clean install. I backup everthing, Time Machine & manual copy or whatever necessary, then try the upgrade. If I rubbed the rabbit's foot correctly, then the upgrade goes well and I continue with my life. Otherwise, if I find issues, then I shug my shoulders and wipe the drive.
In your case, we're assuming that it's a driver that came from Leopard. You don't normally install video drivers manually or individually for the all-in-ones. So if it is a old video driver, you may want to try Googling how to update driver for the MBP. (Not necessarily Googling for Launchpad, just for driver reinstall.)
Maybe it's something else. Just to be certain, have you verified/repaired your disk? If this is the original 200GB drive, then you may have started getting bad blocks or other corrupted files.
In any case, I recommend people consider the clean reinstall methodolgy because there eventually will be a time when your hard drive goes "thunk", so you'll have to reinstall everything from scratch anyway. Or if your equipment gets stolen or water damaged, etc. You do as much as you can before hand but resigning yourself to do a clean install, then finding that the upgrade works just fine is like getting an early birthday present.

Yea, I am trying to avoid the reinstall if I can help it.
Nevertheless, thanks for your insight. I am pretty good with backups so no problems on that front.
If I have to reinstall, I wouldn't want to put all that crap back on anyways
OK - Guess that seems to be the only course.

I had the exactly same problem on my Mid-2011 MBP (Core i7, 4GB with Dual Graphic). Lion installed over SL.
I know this may sounds wierd but try these, they fixed my problem with slow launchpad.
1- try changing your screen resolution to some lower resoulution (like 800x600), launch lauchpad and then change it to your default.
if the previous step didn't help:
I disabled the automatic graphics switching ( in System Preference > Energy Saver ) but I'm not sure this applied to 2008 MBPs.

I have a 2011 iMac and have problems with this , it´s not even the RAM because when i free all of it it still happens. The thing is that when i´m moving de Launchpad page to another it gets reaaaally laggy you can´t imagine how annoying this is, when i use wallpappers applications like "the lost watch 3D Lite" it´s not lagging at all :-S it´s a Lion problem and it´s like a Splinter, I have already formatted the hard drive and installed Lion without leopard, and even without many programs intalled it became laggy again. I tried what you said Ahmadyan but the first thing didn´t word and i failed to find Automatic Graphics Switching in Energy Saver.

Hey, that worked for me here (MacBook Pro 3,1, 8GB RAM). Thanks. Previously it took minutes to go into LaunchPad and switching between screens was impossible; plus the fan cooling the GPU went into overdrice.
Jumped into 800*600, ran LP, fast as lightning; switched back to 1440*900 and it's still fast. Well done. How did you come across the fix?

changing the resolution to 800x600 and back resolved my issue as well. Thanks Ahmadyan.

I see this with latest Mountain Lion with all patches as of 10/15/2012. For me is it 100% caused when I have the Task bar on my external monitor that is driven by my USB DisplayLink external that I use for one of my two external monitors. I fixed the issue by moving the Task Bar to the screen driven directly from my MBA 2011 4GB via the Thuderbolt cable. Will report the drive issue to DisplayLink (yes I'm using their driver for Mountain Lion).
