This is my refurbished Samsung Captivate that I chose as a replacement for several malfunctioning Tilt 2's.  I use this phone for everything, home phone, business email, calendar , primary camera for capturing photos of the kids.  I have had the phone for a little over two years and, although it starts up, she is running sloooow, with 3 o 5 second lag for switcching screens and menues, and 5 to 10 seccond lag for app response, starting up or simple funnctions.  It has been a great phone even through the year long use of Froyo...  I "Need" an HTC One X+ primairly for longevity, amazing screen, great camera, well styled design and battery.  The nVidia quad-core processor gives this phone the capabilities for future Android updatess and I've looked/tried it out at the AT&T store. The phone feels solid, and substantial and is something that I would use for years.  I would love to have one.
Best
Dan
