Hi, I've pretty much decided that I will be purchasing a refurb UMB Macbook, but one of the things that made me hesitant on purchasing this at first were the massive horror stories I was reading on issues concerning displaying the video out either to a projector, monitor, or tv. The specific problem I'm referring to was flickering, where it would flicker so much that it would almost be unusable. At the time of my research, there was no known fix or work around outside for this, but I have not heard this issue discussed recently at all, so I was curious to know if it has been resolved? Also, while I'm at it...does anyone have any recommendations for a good sleeve? I have very specific requirements for this sleeve: -MUST be waterproof. -Must offer some protection, but I'm not expecting anything amazing here. -I would prefer something that is efficient in its design. I don't want unnecessary design elements. If it's just a sleeve, I would prefer for it to be compact so it could fit into a messenger bag comfortably, and if it has a strap, I would prefer that it's still thin enough that it can fit into a larger bag. -Would be nice if it had a shoulder strap. -If it has a strap, would also be nice if it had a compartment that could hold an AC Adaptor and maybe something else (like an ipod), this compartment would preferibly be waterproof as well. -It must be reasonably priced, I don't consider $60+ for a sleeve to be reasonably priced. This (http://www.speckproducts.com/products/tuckpack-sleeve/notebooks-up-to-13/173) sleeve almost seems to meet all of my requirements, but I do not know if it's waterproof, and it is a bit thicker than I'd like it to be. Does anyone have any personal experiences with this? I'm more concerned about the first issue I mentioned, but I thank everyone ahead of time for any help concerning either.
