10MB? oh no! Is your graphing calculator running out of memory?

While I agree that 10 megs is probably overkill for that type of addon....it's really not much when compared to WoW itself. If every addon you use uses that much, you may have problems, but a single addon that replaces so much? I wouldn't worry too much about it.

Also, memory is often used to reduce CPU usage in the future. I can't speak for that addon specifically, but it's a common trade-off in programming.

10MB is a lot of memory? You playing on a 486? Anyway, realty looks decent, might give it a try. I'm looking for an all in one though. Something that gives quest/achievement data and info out similar to carbonite, with the clean minimalism of real in combat. Any advice?

You people don't know what you're talking about. 10MB is indeed a lot of memory for a single addon to use. WoW is only 32bit, and the client it self takes up most of that 2 gigs you can use. You probably only have ~100-120MB for all your addons, less if you like to turn your video settings up.

For raiders, most of that memory budget is probably used up by other raid helper addons; we don't have 10megs to spare.

And people wonder why their client is always crashing.

No. 10mb is not alot. Recount ALONE uses more than 10mb in any raiding situation. And if you say that after you use 2gb on WoW, you dont have "only 100-120 mb left depending on video settings". That's just, not true. And if you have your video settings higher than Everything-Low, you probably have 4gb+ of RAM in your computer.
Like the other said before, 10mb is only alot if you are running using the absolute minimum requirements.

Something that uses "alot of memory" goes into the 25-30mb. Lots of UIs use that much, and no one complains.

This isn't alot. This really is lightweight when you consider it handles everything a UI need.
