Windows 7, more new features were added, but this time a more
disciplined approach concerning OS bulk was taken, helped, in part,
by a large public testing phase. Windows 7 was trimmed down
from Vista both in memory and install size, and many of its critical
metrics (boot time, etc.) approached the high bar set by Windows
However, Microsoft still fell a bit short of the
eight-year-old OS in a couple of critical metrics. According to
numerous testers one of the biggest failures is in battery life on
netbooks. According to recent tests, it isn't even close --
Windows 7 delivers much worse battery life.
grizzled veteran XP, Windows 7 averaged 47 minutes less battery life
by Laptop. In some models, such as ASUS 1008HA, the
deficit was almost an hour (57 minutes), cutting the battery life by
approximately 16 percent (roughly 1/6th). Further testing by
confirmed the lower run times.
comparison by CNET between 64-bit Windows 7 and competitor
Apple's OS X 10.6 "Snow Leopard", run on MacBooks with Boot
Camp showed Windows 7 to trail behind Snow Leopard in battery life as
well. It also was bested by Snow Leopard in boot time, shutdown
time, multimedia encoding, and multitasking tests.
the positive side, it is a marked improvement that Windows 7 can run
on the majority of netbooks -- a feat Vista couldn't pull off.
However, its disappointing to see that for all the hard work
Microsoft poured into the operating system, that it still can't beat
a well-designed product it made almost a decade ago.
