I'd like to have 2560x1440 on a 24" LCD.
As far as LCDs dying go, my 20" LG died after ~4 years, brought back from the dead by changing a couple of 5V caps and a 25V one. I also had a 24" LG (bought about two years after getting the 20") and had to perform similar necromancy on it after two years. The two are now on their 7th and 5th years respectively.
IMO, the standard warranty on LCDs should be at least 5 years and engineering for failure should be a criminal offense similar to fraud - I'd gladly pay $2 extra for the added $0.30 total incremental cost of superior components (about $0.10 per cap x3 in my LCDs' cases and that's a cost difference based on 100s, the difference would likely be well below $0.03/cap when ordering by the 100k) if it lets my $300 LCDs last 7+ trouble-free years instead of 2.
