Hi there, I'll start off by saying that I've never owned a laptop up to now, but after seeing the Retina Macbook Pro I went ahead and shifted to it as my primary computer. I use it both at home and at the office, and for the time being that means that I carry it around with me every day. With winter approaching, I have a couple of questions regarding the proper handling in very low temperature conditions. Apple lists operating and storage temperature ranges as 10° to 35° C (50° to 95° F) and –24° to 45° C (–13° to 113° F) respectively. Just today air temperature dropped to 0° C (32° F) where I live, with numbers as low as -10° C (14° F) not uncommon for February. So my questions are - what precautions should I take when transporting the Macbook Pro outside in these harsh conditions? Should I turn it off prior to taking it outside? How long should I wait before turning it back on once I get inside to avoid condensation and other effects of sudden temperature shifts? I'd really appreciate it if some of the more experienced laptop owners out there can give me a couple of hints. Thanks.
