Currently I am using a sleeve to transport my Macbook Pro (early 2008), however I am getting tired of taking it in and out all the time. However, after much research I am still undecided on which route to go. Here is a comparison from what I've learned through multiple sources: Speck - Many people have reported that it can cause extensive damage to the case. Doesn't this defeat the purpose of using the case if it is just going to damage the laptop anyway? techShell - Some people have said that it dramatically raised the temperature of their laptop due to the fact that it does not have any slots for air flow. Seems pointless to protect the outside of the laptop while you decrease the life of the components inside due to heat. However, I am running smcFanControl. For those with techShell cases, have you found that you can neutralize the effects of the extra heat with increase fan speed? inCase - Will not allow the screen to go back much more than 90 degrees. This is a huge problem to me and the only reason I haven't purchased one yet. I am constantly using my screen at 90 degrees or more. Invisible Shield - Seems that the installation is a huge pain, and knowing my luck, I would mess it up bad. I am one of those people who if it isn't perfect, I will never be happy with it, so a semi-correct installation would just irritate me until I took it off. If any of these assumptions are wrong and you have (or have had) any of these products please share your experience. Thanks in advance.
