Re: Repairable but
I'm a Biological scientist but I used to repair my wife's PSP's including one quite involved bit of electro-surgery. I've also effected a removable drive swap in a Rev B iMac and of course I've replaced the HD in this Mac Pro laptop with a solid state version and a new battery. In the process I discovered why the bottom of the case is distorted such that the RAM chip levers don't push home. One of the battery fix points was broken off with the screw still in it. Some Apple registered repair guy had wrenched it instead of finding the not very hard to see screw and removing it.
I informed the younges who handed the machine up to me so she knew the quality of the service she had been getting.
So don't diss us home amateurs in possession of a wide range of micro screwdrivers vs the supposed pros. Those in it for the money have a vested interest in taking short cuts to avoid spending too much on the job whilst us amateurs generally have more time to do a decent job.
BTW I have some of the steadiest hands in the micro dissection/small animal/embryo surgery business so transferring that to compu-surgery is actually pretty easy because I don't have to do it under a dissecting scope.
