the dreamcolor for laptop is nothing like dreamcolor lcd's. laptops just have a whole (lower) quality of standard for screen compared to their desktop counterpart.
keep in mind your average monitor which isn't worth a boat anchor probably wipes the best lcd's butt in performance.
go bust out that ole princeton 21" and calibrate it against your (ips/mva/pva) and see how it stacks up (input lag, color accuracy, black levels). in most lcd's that we can afford the $10/monitor sitting on the side of the street will put to shame most desktop lcd's. and laptop lcd's are a notch even lower.
the elitebook 8730w dreamcolor is nothing great. maybe as good as the older macbook screens before they went cheap.
definitely nowhere near the lp2480zx i have which is a decent 30-bit (with LUT's)..
The HP Envy series DOES NOT have an IPS or PVA / MVA panel. It does, however, have a much higher quality TN panel that has respectable viewing angles. Make sure you go with the "Radiance display," though.
In all honesty, a good quality TN panel isn't that much worse than an entry level IPS panel. The differences between my EA231WMi and my Envy 14's screen aren't drastic in terms of color, contrast, and viewing angles. The EA231WMi does edge it out, but I wouldn't object to using the Envy 14 for anything other than serious photo work.
Corky, what is that great big piece of analogue kit next door? Something to do with audio?
