Multiple Apps / Battery

[sracercelica]

I hate waiting for apps to load up, some are pretty fast (2-3 seconds) but some can take longer (4-10 seconds). I specially hate waiting for the apps I used very often to load. I know that one of the good features of WM is the ability to have multiple apps opened at a time. Therefore I was thinking of leaving all my most used apps opened all the time (google maps, opera, text msg., email, live search). That way I could just switch between them using the task mgr. and wouldnt have to wait for them to load.

However, by leaving these apps opened all the time, will my battery take a big hit? I mean since they would all be in stanby pretty much would the battery drain pretty fast?
