Several analysts have issued new memos in the wake of Apple's Q1 financial results. Kaufman Bros.' Shaw Wu notes that the results were the "strongest in the company's history," helped mainly by greater-than-expected Mac sales, and a shift towards higher average selling prices for Macs, iPods and iPhones quarter-over-quarter. The 8.7 million in iPhone shipments is described as being "light," but Apple has claimed in a conference call that it could have shipped more if it had not wanted to keep inventory tight.
