X900e owner here! If you can swing it, you won't be disappointed. In terms of PQ and performance, the X900e has no real weakness--it's good at everything. Very good blacks, excellent contrast and color. Outstanding upscaling and motion performance--might be the best set for watching live sports, regardless of price. The only weakness is the Android OS implementation, which I personally don't find that bad. YMMV, of course.
My humble system:
Sony X900e; Sony UBP-X800; Pioneer Elite BDP-62FD universal blu-ray player; Denon 4300H AVR, Dual PSA S1801's; Monitor Audio Silver RX-6 mains, RX center, and RX surrounds; one pair NHT mini Atmos speakers; Home-built HTPC (Xeon E1230, 16gb RAM, Crucial M500 480gb SSD, GeForce 980Ti, Corsair CX600, CoolerMaster mini-ITX case)
