Lenovo's X230T is the performance leader among the tablet PCs we've reviewed. It employs a much faster processor with a 35 W TDP, compared to the 17 W part in Samsung's Series 7 11.6" Slate. In truth, the CPU is only one factor in the PCMark 7 results, though. In our review of the Samsung system, it was able to outperform a faster Sandy Bridge-based notebook, also with a 35 W CPU, specifically because the Series 7 included an SSD.
And thus, storage becomes the real story here. Intel's Ivy Bridge architecture certainly delivers a performance benefit, evidenced by CPU-bound subtests like "Web Browsing with 3 Tabs" and "Text Editing." However, the X230T suffers due to its conventional 7200 RPM hard drive, falling behind in the storage-based tests. Even Asus' Eee Slate, equipped with a low-quality SanDisk P4 SSD, outdoes the X230T.
SSD prices are now falling well below $1/GB, providing ample incentive to upgrade any prospective system purchase. Unfortunately, ordering an SSD-equipped Lenovo X230T is quite costly. You'd be better off performing the upgrade yourself and cloning the tablet PC's disk using a utility like Acronis True Image. At the very least, it wouldn't be difficult to propel the X230T's storage performance to match faster storage subsystems.
