One of my clients found themselves overdue for ordering new PC laptops for their business, but were out of options: the Dell Latitudes they'd bought over the last five years had not held up well, and the HP laptops they bought more recently couldn't accommodate reasonable upgrades and were heavy and unpopular with users.A key factor in suggesting the MacBooks was that Apple delivers products with known abilities. It turned out that the HP laptops they had been buying couldn’t be upgraded with a larger hard drive. There was an unadvertised, artificial limitation in the size of hard drive the HPs would accommodate, and HP support didn’t seem to know why a 2006 laptop couldn’t use an 80 GB or larger drive. They also couldn’t explain why a stock hard drive wouldn’t work, and could only recommended that we buy HP branded drives. Insane.
