Weight – What reviewers say Reviews praise the responsive performance and bright screen. Macworld found modest gains over the previous Core Duo generation and performance close to the 24-inch model, but criticised costly memory upgrades and limited expansion. ASCII's display tests found smooth colour gradations suitable for creative work, with some contrast change when viewed off-centre.
