I'd look into a T/W530 myself for a Thinkpad, though.
there are some T530s with 1600x900 panels at the 600 mark in the outlet, you'll have to go over budget if you throw an ssd in there but it'll be worth it.
I swear by thinkpads, good build quality, good input devices (learn the trackpoint, love the trackpoint and your hands will never have to leave the keyboard - which is one of the best you'll find in a laptop), very servicable and professional looking.
Starting a new job soon, and I'll be telecommuting so I need to look into a good laptop. I'm shooting for a 15" around the $600 range that has SSD and will allow me to dual boot into Win and Linux. I'm really not finding a whole lot online, anybody have some suggestions?
The L530 and T530 900p screen is not that good and the T530 is more expensive. Better get the HP above and in the worst case - simply replace the HDD
You could always consider a Thinkpad from the Lenovo outlet... there's an L530 going for $437.57 right now that has the following specs:
Processor: Intel® Core i5-3210M Processor (2.50GHz, up to 3.10GHz with Turbo Boost, 3MB Cache, 1333MHz)
Operating system: Windows 8 Standard 64 - English
Display: 15.6" HD+ (1600 X 900) LED backlight
Graphics: Intel® HD Graphics 4000
Memory: 8GB (2 X 4GB) PC3-12800 DDR3 1600MHz SDRAM SODIMM Memory
Hard Drive: 320GB, 7200RPM Serial ATA 2.5" Hard Drive
Optical Drive: DVD Recordable Serial ATA
Tack on another $100-120 for an msata SSD and you're good to go. That way you can keep the mechanical HDD while adding an SSD. I'd look into a T/W530 myself for a Thinkpad, though.
