Hard drive is officially the bottleneck on the development laptop.  Of course that isn’t news, but on this Dell Precision M4400 laptop (Intel Dual Core, 8GB RAM), I’m still looking for a solution to the hard drive problem.  Intel X-25 series looks promising, but if SuperSpeed would hurry up with SuperCache for Windows 7 x64, the problem might be solved through RAM and software while retaining the reliability of magnetic disks.  We’ll see.
