I'm thinking of using Rainmeter, after seeing the Metro theme for it in this thread (looks awesome!). One thing that's stopping me is memory usage, considering how much a resource hog some UI customization programs are. How is Rainmeter with memory?
Memory for Rainmeter depends on the skin. For the most part it is extremely light on resources.
The Metro skin, however, can take up some memory if you enable and use everything. For the most part though it's manageable on a modern computer.
*edit*
Sorry for not editing the OP in a while, I've kinda settled on my desktop for now and haven't been browsing for skins as much. I'll make sure to keep things updated in the Q2 thread though.
Problem is it's at the text limit, can't keep everything in one post.
