So the news is out.
The MacBook, now for sale, has a 13 inch widescreen display (1280 x 800 where I had anticipated closer to Sony's 1366 x 768), a mini-DVI output which requires an inexpensive (15 GBP) adapter for either a DVI or VGA socket on your display. It also features the dual-core CoreDuo processor, from 1.83GHz, where many expected to see a "CoreSolo" for the cheaper end of the range.
The anticipated black finish is only available for the 2GHz 80GB+ model, at an 89 GBP premium! Its budget nature is revealed, however, when considering the weight: The MacBook weighs in at a sizeable 2.36kg, comparing unfavourably, for example, to the superiorly configured Sony VAIO VGN-SZ110B, which weighs only 1.86kg.
We shall have to wait for news on battery life (not expected to diverge from the MacBook Pro), thermal paste, whine and MagSafe. Some people are curious about GPU performance.
