The Macintosh LC was a low cost computer designed for economy. The LC (LC for low cost color) had a relatively powerful 68020 CPU, but coupled to a 16-bit data bus, it accessed RAM slowly. Its RAM ceiling of 10 MB made it obsolete way before its time. The LC's most compelling aspect was its price. At $2,500, it cost a fraction of the $6000 plus price tag of the Macintosh II, and could generate 8-bit video in 256 colors (16-bit at 512 x 384 if using 512K VRAM). Color had never been as affordable on any Macintosh until the introduction of the LC.
