FFS man, its Merom, not Memron. There's like 20 people that I've seen making this mistake.
To Ulater's original question, the Merom is the Conroe for Laptops. The Core Duo processors (Yonah) are great and stuff, and match AMD's clock-for-clock performance, but they lack 64-bit support. The Core 2 Duo (Merom) processors, aside from other advantages, increase the clock-for-clock performance to Conroe's (which is much higher than AMD's) and adds 64-bit support. The Merom processors are drop-in compatible with Yonah, so if you bought a Core Solo/Duo laptop, you can disassemble it and just plop in a Core 2 Duo Merom.
