Build quality of Precision M4400 vs the M65/M4300 ?

How is the Build quality of Precision M4400 compared to the M65/M4300 ?

I was taken aback by the following post:

 

Well,the point's pretty moot as dell don't make M65 or 4300's anymore,but you know how I voted

 

You know, if you ask me, the D-Series chassis of the M4300 is like a Gameboy Color and the E-Series chassis of the M4400 is like a PSP. I think both are built very well when it comes to fit and finish, but the current E-Series machines are built more like a luxury car and the late D-Series machines are built more like a hummer. You'd prefer to drop your Gameboy Color than your PSP if you had a choice. At the same rate, you'd prefer driving the luxury car on a day to day basis, but you're going to prefer the hummer if you ever get into an accident.

So if that's helpful at all...
