Reviews are starting to come in on both the new 21.5- and 27-inch iMac models, with the general consensus that both are lightning-fast (faster, in fact, than any comparable 27-inch Windows-based machine), offer much less reflectivity and a better display, and are gorgeous to look at. They also note some changes, such as the relocation of the memory ports (which are upgradable), and a reduction in quality of the built-in speakers (likely a sacrifice to the thin design). Though considered pricey, the new iMac is still thus far seen as being the best AIO computer around.
