Windows 7 - [Help] Purchasing new laptop

Hello,

I am purchasing new laptop. I am tired with boot speed & performance of SATA drives & want to go with SSD.

Currently, I am comparing
XPS 17 Laptop - Feel the Thrill with 3D Laptop Screen | Dell
&
XPS 15z Laptop Details | Dell
&
Premium Laptop, Professional Audio Laptop | HP Envy

My requirements are

-> Slim & Stylish
-> SSD drives for OS & Sata for data
-> Long battery life
-> Shouldn't more than 7-8 lbs

Remaining things like Processor, RAM etc any thing will work from Core i7 range & 8GB will be good. Not high end gaming cards, just normal will work. I don't want any heating & rebooting issues.

I hope someone will help to choose some good laptop.

BUDGET is not an issue.

Waiting for some responses.

Regards

Well given the three choices I would automatically lean toward the HP. I have a grudge against Dell, they don't stand behind their products and their tech support is hopelessly useless. I've had good luck with the HP machines I've worked with. I currently run an Acer *See my system specs. that has been great. They just released a bunch of second gen iCore powered machines, might be worth a look.

A bit of friendly advice. Nobody's going to go through all those links for you- esp. given HP's terrible website. if you want serious rational opinions, pull out the datasheet for each of those models, compare specifics (cpu vs. cpu, gpu vs. gpu, ram vs. ram etc.), then ask specific questions about features that interest you.
