I wouldn't recommend and HP. Sure, they have a lot of bells and whistles, but they are like a Jaguar - pretty and perform, but in the shop half of the time.
I have had to send my laptop back to HP so many times.
Such a hassle that I would trade off the bells and whistles for something else.
If IBM were still in the business, I would definitely go back to one of their machines - never, ever crashed. Ever. I don't know if that is the case now that they are Lenovo, but maybe read some reviews - if they seem to say the quality is similar to IBM, go for it...in a NY minute.
Otherwise, the Vaio seems good and stable, but pretty expensive.
So, that's my experience. Hopefully, Ringel will post - he knows the hardware, so I would listen to him.
