victorintelr,
your x230t has a regular voltage cpu while this one has the wimpy (compared to regular voltage) low voltage cpu. So it really depends on what you want to do with your device. Low voltage cpu's are still plenty fast for web browsing and office work. If you want to make your x230t run like an Ultrabook, all you need to do is restrict the cpu performance to 80% or so in the power manager. That way, it uses almost the same amount of power as a low voltage cpu, with the same performance. You won't even hear the fan if you do this. Idle power usage are very similar between regular voltage and low voltage cpu, and load power usage at same clock speed is also very similar.
I also have a x230t, with i5 (for about $1000 with 3 year warranty), and I love the expandability and quietness at full load. Can't even dream of this performance on an Ultrabook. But I have to admit, x230t is very bulky and heavy.
