Sounds good. On my desktop computer, weather and rss 
update only every 30 minutes here, so should be 
minimal strain. Picture frame, when I use it, changes 
every 2 minutes or so, so that would suggest somewhat 
increased load, but also minimal.

Again, you have stilled my concerns, so I can likely 
even begin using plasmoids on my 3.5 year old laptop, 
where I always refrained, due to concerns about 
sapping processor power :-)
