Up to 8 hrs, is like Starting From... Both are Marketing Approximations, and are likely to be rosier then reality... It depends on how many apps are running at the same time etc., type of usage varies, as well how bright the screen is, or if Blue Tooth is on etc.
But, even if the reality is TRUE 5-6 HOURS no matter how hard one is running this MBP Unibody 17', than it's still GREAT!
NYC to Tokyo is 14 hrs? How likely is one to WORK 6-8 of those hours, or to use those to watch 3 x 2hrs movies?
14hrs minus 6-8 of those hours = leaves 6 or 8 for SLEEP, and FOOD! People on those flight are gonna need both, and badly, to compensate for time change!
Also, if one is taking an EARLY flight, after not enough sleep, how eager would they be to WORK on that machine? They'd be trying to steal some SLEEP?
Or, if it's a LATE FLIGHT, they'd try to get in some SLEEP too!
Everywhere else, except for OURDOORS (Jungle, Desert) they'd have power in the car, bus, train, so that the batter is not an issue!!! But if it's serious OURDOORS, then they'd carry some PORTABLE POWER, Solar, or GENERATORS, so...
Up to 8 hrs = TRUE 5-6 HOURS no matter how hard one is running this MBP Unibody 17', than it's still GREAT!
Of course, after YEARS of always worrying about running out of battery power it understandable why people would be concerned... But, like I already mentioned earlier, SOMEONE will make PARTABLE EXTERNAL PACKS for this, and the problem solved for next time one is in the jungle!
The other Q is WHAT COUNTS AS A CYCLE! If one starts charging at 50% is that ONE CYCLE or HALF a CYCLE?
If HALF, like is supposedly the case with iPhone 3G, then this battery will last LONGER than 1000 : 365 (1 day = 1 Cycle) = 2.739726, and in THEORY, if 1/2 Cycle per 1 Day, it's 2.739726 x 2 = 5.479452 = Almost 5.5 YEARS?! So, even if it's 4 TRUE YEARS! - it's pretty good, right? Then, a few screws, and the SAME or BETTER BATTERY could go in for 1/2 the price, or at least LESS than what it is TODAY!!!
As USUAL, the Devil is in DETAILS, right
Also, with FW400 gone, we'd need Converter Cables. I am thinking about my Optura 30 MiniDV Camcorder (2004-2005)
What's the NEXT BIG THING? WiMax, LTE, 3G Built In? And how badly will they eat THIS battery, or whatever follows it?
Then we'll have another article here, and a few more INSULTS
! Hey Mac users are supposed to be a PASSIONATE BUNCH, so I guess it's normal, but I'd still rather not see INSULTS
HAPPY UPGRADES TO ALL
