I have not yet removed the (green-tinted transparent) plastic cover from the side of my P50. I am talking about the one that covers my Expresscard and SD card slots. I had initially not known that the Expresscard slot has a spring-loaded door on it, and was keeping the plastic on as a dust cover (especially since it doesn't cover the vent) until I had something to populate the slot. However, over Thanksgiving Weekend, I noticed that the Expresscard does, in fact, have a spring-loaded closure.
The SD slot (halfway cut into the slope on the bottom) has a rather big opening (because of the slope of the plastic.) (Please see the pictures: http://oi68.tinypic.com/10f2492.jpg, http://oi68.tinypic.com/r7qcr5.jpg, http://oi64.tinypic.com/33d8109.jpg, http://oi63.tinypic.com/egsi6c.jpg, and http://oi64.tinypic.com/jrxmav.jpg)
My concern is dust, crumbs, and random debris getting in and harming something.
My question is:
Is it worth the bother of plugging an external SD card reader into a USB port to keep dust out of that SD card slot?
Should I populate that slot with an SD-to-micro-SD adapter to plug the hole, and then just swap it out for a SD chip when I need to, not worrying about safely removing the adapter, as it isn't a memory-storage device?
Or should I just go ahead, remove the plastic, and not worry about dust, etc potentially building up inside it?
Thanks very much!

I cannot say what you should do, but I have used several machines with similar slots, and I have never covered them. I have not had a problem.

I've never had a problem with foreign object ingress in any of the card slots for my various ThinkPads dating back to the PCMCIA days. That said, if you want, you could insert an SD Card into the slot to act as a blanking plate.
If you are working in an environment where foreign object ingress is a problem, you might want to consider a set of port plugs like this, this or this (given as examples only, you can find them at many other online stores).

Thank you Richk and Goretsky! After reading your answers, I doubt that I will worry about it, remove that plastic, and at most plug a blank SD card in if it becomes a problem.
Also, thank you, Goretsky, for pointing out those port covers!
The P50's Expresscard 34mm (Gen 2) does have a spring-loaded cover on it. (I had initially and wrongly thought that it was open.) My question had been about the SD card slot just below it. This picture seems to show that the same is true (spring-loaded cover=present) on the P70.

I just keep an old Wintec 48GB ExpressCard/34 SSD in my ExpressCard slot. No dust ingress noted.

Actually, there isn't a spring-loaded cover, just a plastic filler card. You can purchase one off of eBay or Amazon to install in the ExpressCard slot. Be sure to get a 34mm wide and not a 54mm wide model.
