I have one of the earlier Samsung hybrid monitors, the SyncMaster T260HD, which has a 25.5" screen. The TN panel in it causes some problems, especially viewing at an angle below the level of the screen. The prices on the 30 series would lead me to believe they also use TN panels. It would help to have a link to the manufacturer site to examine the specifications of these new monitor/tv's.
I personally wouldn't get another screen this size unless it uses a different type of panel, like an S-IPS or S-PVA panel.
