Debating between a few different ultrabooks

[albo23]

So I am in need of a new ultrabook and I have narrowed my search down to four. I am hoping I can have some computer experts can help me determine the best value for my buck.

{Acer Aspire S7-392-6807} -- $1,169. 13.3", i5-4200U, 8GB, 128 SSD, 2560 x 1440, .51" depth

{Sony VAIO Pro 13 Touchscreen Ultrabook SVP1321DCXS} -- $1,199. 13.3", i7-4500U, 8GB, 128 SSD, 1080p, .68"

{Samsung ATIV Book 9 Plus NP940X3G-S03US} -- $1,304. 13.3", i5-4500U, 8GB, 128 SSD, 3200 x 1800, .54"

All three have their pros and cons.
The Acer has the lowest price, is the thinnest, and has 1440p. The negative is that it's only an i5.
The Sony has the i7 processor, but it has two negatives in that it is 1080p and is the thickest.
The Samsung has the best resolution but it is only i5 and is $150 more than the Acer.

Is Sony's i7 worth the drop in resolution? Is Samsung's 1800p resolution worth the extra $150? Or is the Acer the best all-around package?

If I remember correctly, the only difference between i5 and i7 is the extra 1mb of l3 cache the i7 has. Both are dual core CPU's with hyperthreading. I would personally get the one with best battery life, build quality and more than 128gb of storage and at least 8gb of RAM.

One thing you didn't post was weight. The Sony is at least a half-pound lighter than the other two options. The trade-off is that it's the least solidly-built of the three systems.

And just a tip - those ultra-high resolutions really aren't very useful on a 13.3" screen. I'd personally get the Sony from among those choices, but I'd recommend you also look at the Lenovo Yoga 2 Pro.

ThinkPad X240

With its extended battery, the 12.5-inch, 3.6-pound ThinkPad X240 lasts an amazing 20 hours and 28 minutes on a charge, long enough to pull an all-nighter or work on the entire flight from New York to Taipei. Add in a bright IPS touch screen, a powerful Haswell processor and a wide array of ports and you have a portable productivity powerhouse.

I agree with this, especially if you're running Windows. DPI scaling in Windows 8 is better than it has been in the past, but it's still a mess once you venture outside of the Metro walled garden.
