I currently have a hp envy 17-3d with the 1080p tn panel and it is good but was curious what reasonable desktop setups were being used most importantly monitors that do not cost $1k +. It must be windows sorry but I get all the software free. Also if you use a laptop which model?
First thing - If you want a good, comparatively cheap monitor for editing - the Dell U2410 is a great choice.
Okay, on to my setup:
For mobile, I have a Dell Precision M4600 workstation w/ 15.6" 1080P TN (70% AdobeRGB) panel. The internals could be beefier - my unit is only dual core (i5 @ 2.6GHz), 4GB RAM - although the chassis is quad-core ready and good for up to 32GB RAM, should I ever get the upgrade bug. AMD FirePro M5950 graphics card, Storage is an Intel 160GB SSD, and I've thrown a copy of Adobe LR4 on it. The LCD, while not IPS, is still better than 95% of the laptop screens I've seen - really, it's a pretty great panel (although my desktop IPS and S-PVA display blow it away). The laptop was a kick butt deal at $830 refurb'ed (including a 3 year warranty) from Dell Outlet.
At home I use a self-built desktop. It's getting long in the tooth and a rebuild is imminent (waiting for Windows 8...), but here are the current (relevant) specs:
AMD Phenom 4 9850BE @ 2.5GHz
MSI K9A2 Platinum MB
6GB DDR2-800 RAM
Radeon 6950 2GB graphics (shader-unlocked to 6970)
OCZ Vertex 2 SSD 120GB boot drive
A few WD 1TB 5400RPM storage drives
Blu-ray + DVD-RW drives
Win 7 Ultimate
Dell U2711 monitor
Dell 2407FPW monitor
Canon 9500 Mk II printer
3TB RAID-1 (dual Seagate 3TB 7200RPM drives in parallel) in a Dlink DNS-325 NAS
2TB 7200RPM Seagate External USB 3.0
A few more small external drives for travel
Desktop rebuild will probably look something like this:
Z77-based MB with plenty of SATA ports
New, larger (shooting for 256GB) SATA 3.0 SSD
Photoshop CS6 (already have a copy waiting)
Scavenge the rest of the parts from my current desktop
