Summary: SVF1532APXB, There are several improvements over the SVF15A190X that I just returned due to Wi-Fi issues, fan noise, and hot spot in the screen, but the new model has the same Wi-Fi problems. Wi-Fi speed on my old VGN model and a Dell laptop are around 56mps download and 33mps upload. Both Vaio Fit models that I purchased average 7 to 23mps download and 28 to 32 upload. I am testing the computers within 15 feet of my router.
Summary: I have the Vaio Fit 14" with the intel i5 6 gig ram and 750 gig hard-drive. The computer is powerful, stylish, and gets everything I throw at it done. Miner lag when playing certain video games. But does amazing when I am working on large files on PhotoShop CC and AfterEffects. Highly recommend this laptop!
