comment What happens when an SSD wears out?
@Ark-kun Fair enough, but I don't consider the failure mode of either to be "graceful" personally. Having the OS brick for a power user, isn't as big a deal as it is for your standard consumer. This is why a good, and ideally mostly transparent to the user, backup system is an absolute must, and why I refuse to acknowledge "graceful" failure modes. Without a backup, there's no way to be sure you're not going to lose data.

comment What happens when an SSD wears out?
@Ark-kun I have said nothing to the contrary, however, in my experience, end users tend to put up with the finickiness of their computers while the HDD fails, up until an OS Update is required. When that happens, the multiple write errors brick the OS and make the computer fail to boot. HDDs handle bad sector relocation internally by now. (1 bad sector) If you're seeing data errors, the HDD has already run out of spare relocation sectors, and you're already staring down the "many bad sector" scenario. That's where SMART can help, because it warns when relocation sectors are running low.

comment What happens when an SSD wears out?
@Tobu, it would be great if all OSes popped up warnings and really alerted the user when a SMART failure was noticed, but even that is only about 50% according to Google and their massive experience with drive failure. I've seen both Windows and Mac OSX fail spectacularly during Software Updates with a failing drive. In neither case did SMART help or predict the failure. It's also pretty weak sauce to say "users who ignore it". USERS WILL! It's the SO or SD's responsibility to ensure that doesn't happen. Vista's incessant popups didn't help with the ignoring it problem either.

+1 - My suggested solution as well. I've used this method to combine several PDFs by printing, then choosing "Save as PDF" from the print panel.

@DragonLord You sure about the "no damage" part of that? Many electronic devices will continue to function, even in a damaged state, only to fail later due to inexplicable circumstances. You might want to keep good notes about when that incident occurred, and any strange behavior from here on out.

comment What happens when an SSD wears out?
I object to the assertion that HDDs "degrade gracefully over time". In my experience, by the time they reach the failure mode that most people notice, they've been thrashed by the OS enough that data recovery is often quite difficult. The most common time I see HDD failures noticed is after running software updates, when the corruption affects the OS and in essence bricks the computer from the user's POV.

comment My MacBook Pro (2011) is dead
I had a device short the USB port of my 2009 MBP 17", and all it ended up doing was giving me an onscreen warning that it had disabled the USB port due to shorting, and please disconnect the device. Your experience is surprising given what I experienced. The device in question was a wireless headset with USB charging.

+1 - But I would also recommend making sure the system has enough RAM as well. Make sure you have 8GB, not 4 in your system, (It really is barely enough under Lion) and spring for the faster CPUs unless you're going to be processing GB upon GB of data. (Drilling surveys, nuclear bomb simulations, that kind of thing) If you need more/faster storage later, you can always use an external box connected to Thunderbolt. CPU is impractical to change unless you're going for a Mac Pro.

comment What is the wi-spy usb hardware used for?
The short answer is yes, but remember that not all sources send at the same time, or with the same signal strength. The desired equipment may be able to "override" the strength of a farther away signal, or you may get perfect signal at some times and not others. Particularly insidious is that if you move away from the desired source (in the direction of the further away source) then your signal quality will degrade VERY FAST as your desired signal strength decreases, and the undesired source's strength increases.

+1 for a good answer, and the recommendation of Google Apps standard.
