But now, there's a whole class of power-saving, low-cost nettops like the Acer Aspire Revo R3610 that are infringing on the mini's turf. Fast forward to 2010: The Apple Mac mini is still the entry point for the Apple faithful and it continues to be a good, cheap computer. Back then it was the only ultra small form factor (USFF) desktop worthy of the name (6.5-inches square, 2-inches high). The Apple Mac mini (Core 2 Duo 2.26GHz) ($599 list) still looks just like it did when it was introduced in 2005.
