This is so true. With other leading companies, you'll often see a product and it'll be so well designed and everything will be so thought out, that it'll bring an instant smile to your face. With Microsoft's products, on the other hand, you're often frowning the minute you open them.
Just today, I fired up Entourage (MS Outlook for Mac) over a really flaky connection; and the first thing it does is update the Bulk Mail folder. Really, Microsoft? Would that be my first priority when I open an email client, to see what new junk mail has arrived? Then it proceeded to update other sundry folders, and near the end it did it update the Inbox (which is what I was waiting for).
