That is their main problem, but it's temporary. Motorola has done an abysmal job with G4 development, which is why later this year Macs will get PowerPC 970 processors from IBM. And even today they can make money on their hardware, note that after nonrecurring charges they had a profit.
Gates already bailed them out, didn't he?
No. You may be thinking of the stock deal from a few years back, which was the public part of a large settlement regarding MS patent infringement.
If Apple were smart, they'd get out of the hardware business entirely, and go into competition with Microsoft.
While "go into direct competition with Microsoft" is rarely a winning strategy, Apple is prepared if Microsoft decides to fire the first shot. Keynote is a not-very-subtle message that Office is replaceable if MS halts Mac development.
I'd say it's only a matter of time before Apple goes under, unless they make some very major changes.
Yes, that's as true as it was when I read it a few years ago. And in 1997. And 1995, 1992, 1990, 1988, 1987, and 1984.
A lot of people would be glad to replace Office if something else even became close to standardized. The costs for licensing are enormous for large companies. Replacement with Open Office or something similiar is a trickle now, but...
