Heh, I wish I could try one out.
There isn't a decent electronics store within 100 miles of here. I was thinking of going on Wal-Mart.com and buying one just to see if the input lag was irritating, then return it locally... but they don't even sell any IPS or PVA panels.
Staples is the closest electronics store, and they don't sell anything. They have like 10 monitors on their website.
Even BestBuy has a terrible selection of monitors.
