The reason I have started to think about this is I have a Win XP Duo
Core processor with 2GB of Ram, and I am amazed at how slow Photoshop
CS3 loads, especially when I compare the speed of Photoshop CS3 running
on an older Mac. I might be buying a new computer sooner than I
normally do.

This is an example of the articles I have read that have started me
thinking about buying a Mac when it is time to upgrade:

October 29, 2007 (Computerworld) -- Apple Inc.'s computers are the most
reliable and its support the most dependable of five top vendors, a
national chain of computer service shops said today.

Macs beat machines built and sold by Lenovo Group Ltd., Hewlett-Packard
Co., Gateway Inc. and Dell Inc., according to Rescuecom Corp.'s second
annual reliability report. Apple, which took the second spot last year,
blew away the competition this year by posting a score 51% higher than
the next-best, Lenovo.

To come up with its scores, Rescuecom compared the percentage of each
company's support calls with its market share, said David Milman,
Rescuecom's CEO. The greater the difference, the higher the score, and
the better the hardware and follow-up OEM support. Apple, for example,
received the highest score because Macs made up only 1.4% of all calls
to Rescuecom, even though its estimated market share was 5% for the
year. Dell machines, on the other hand, accounted for 34.5% of all
Rescuecom's incoming calls, which was higher than the company's 32.3%
market share.

"It takes into account not just the quality and reliability of the
equipment," said Milman, "but also the quality of service." The two are
equally important, he said. "If a user is calling Rescuecom, that means
they've abandoned the manufacturer's own support."

Apple led the five vendors with a score of 347, followed by Lenovo/IBM
(236), HP (126), Gateway (103) and Dell (94).

"Apple's score tells me that it has both great quality control and great
support in place," said Milman. "And that Apple is taking care of its
customers though its internal support channel." Unlike the other four
vendors, Apple has its own retail chain, whose stores are manned with
customer support personnel, dubbed Apple Geniuses.

Dell, on the other hand, is now at the bottom of Rescuecom's scoring
system, having slipped from last year's fourth place to fifth this year.
"Dell faces some challenges to deliver quality products and quality
services," said Milman. "The probability is certainly higher that a
customer will have problems with a Dell than with an HP or a Lenovo
[computer]."

The Round Rock, Tex. computer maker's has had problems meeting customer
demand for some laptops, and has seen its once high-flying service and
support reputation drop. In August, for instance, the American Customer
Satisfaction Index (ASCI), a barometer of customer satisfaction produced
at the University of Michigan, pegged Dell's score as down four points
from the previous year.

"Dell isn't going anywhere," said Milman. "They still have good
machines. But over the long run, you're more likely to have a problem
with Dell."

In the same ASCI of August, Apple scored 79, the highest among the seven
makers and/or computer lines, but like Dell, also down four points from
2006.
