i had the lg optimus 2x/speed for 2-3 weeks. When i bought the device i wanted to take a look at android and the ui (it was my first android phone). I have heard a lot about multitasking in andorid, that its "some kind of" ok, that its not real multitasking, and things like that, but i have tried to make my own opinion.
And then, after using it for some time, my things i mostly dislike at android is the way i have to close an app and the way how the (open) apps are presented to me.

Closing apps means pushing the back button (many times) until you are in the main menu/desktop. So its not possible to close a game while you are ingame, without pushing this back button sooo many times...
(N900: 1 click to get into the task manager, another click for each window to close it)

and yes, i am starting more then 1 app or function and want to be able to change between them, to e.g. copy&paste text from an email to the sms window or the editor.

while using the lg speed and opening apps and change between apps i never felt that i was multitasking, it was just something like "close an app, start another app, then close this app to start another app".

and regardin the task manager at android... i thought they would be kidding (the guys talking about multitasking ) if i push the home button longer, i get that... ehm... lets call it "task switcher". Isnt it just a list of the last opened apps!? i mean, i want a task manager where i can see exactly which apps are open and which are already closed (closed!=freezed; closed=free up some ram), really closed.

Before N900 i had only symbian phones since 7650 (someone remembers that fat boy? i loved it soooo much, first real smartphone ever ), and the first version symbian better multi tasking abilities then android or ios.

I am a N900 User started from day 1, and from that day on i had a very good sleep with my device (like with every device before) but with the lg speed it wasnt the same feeling, it was just there lying around, but didnt gave that nice mood i get when i have a new gadget...

P.S.: in the weeks i used the lg phone i was sometimes in the official german lg blog... i told them what i think about the device (nice hardware, poor and laggy software) and about the multitask abilitys of android... and the guy from the blog told me that android has the best multitasking compare to every other os... so they are still kidding me...

just my 2cts, i need mt i want it, its one of the biggest reasons i love this device and this os so much!!
