Wow pretty nice! Looks like they dropped the MSRP $50 and applied the current 10% off promo. If I get a 10% off mailer in the next few weeks I might have to pair this up with my Gateway. Also, I don't think Dell Home charges tax in states/provinces where they don't have a Kiosk. Pretty sure I can get it delivered to DC and avoid tax.
Edit: If you're going to use your LCD purely for PC and PC gaming, then the 22" to 24" probably isn't worth it but..... the 24" uses an S-PVA where most of the 22" use a TN panel. The 24" also can do 1080p native with 1:1 pixel mapping and has the inputs to put it to good use. The extra 2" isn't anything to sneeze at but its not worth 2x the price by itself.
