I also read the Macbook Pro review, and indeed it looks like one of the best Macbooks so far, if not the best.
When comparing it to the X301, both have some advantages and disadvantages.
For reference:

CPU and GPU performance: MBP will blow X301 out of the water, no questions asked.
Screen: Not as clear-cut as you may think. Sure lots of bad water has been spilled on these forums (and not only here) about the X301 screen quality, but the MBP does not seem to be all that better. Perceptive contrast is the only thing that will probably be better (in part due to the glossy coating), but the viewing angles don't seem better at all (refer to reviews), and the glare is bothering under certain conditions. Also, the X301 screen is higher res, which is an important advantage for some (albeit a possible disadvantage for those with weaker eyesight).
Battery life: MBP has an advantage, not an overwhelming one, but it exists. This can be partially by using an Ultrabay battery for the X301, in lieu of the optical drive. Also, as reported in the review, the battery life of the MBP in Windows is not as stellar as in MacOS, due to poor power management functions in the driver.
Ports: A mixed bag here. MBP has Firewire and the SD Card Reader. However, overall I think the X301 has the advantage here, with VGA, DisplayPort (don't forget, Mac's Mini-DP is not a standard port, and only works with a proprietary Apple adapter!), 3 vs 2 USB ports, and better placed ones. The ones on the MBP are so close to one another, that for many practical purposes you only have one USB. As far as business-grade expansion goes, both are equally poor with no PCMCIA/ExpressCard and no docking capabilities.
Build quality: I think both are going to be very very solid, shouldn't have issues with either one.
Keyboard: Apple's keyboards are very solid with no flex whatsoever (due to the unibody construction too). Typing on them takes a bit getting used to, but is mostly fine once you do. However, the layout is different. Apple layout is naturally more tuned towards MacOS, and lacks some commonly used Windows keys (Home/End/Pgup/Pgdn). The X301 keyboard is the classic Thinkpad layout, which is excellent too.
Mouse: In the world of touchpads, no one can beat Apple's multi-touch. However, the X301 has a serious advantage in the form of a trackpoint, which I, like most on these forums, find far superior. But this is mostly personal preference. One or the other laptop will be better for you, depending on your preference for input device.
Weight: Don't forget that factor! The MBP weighs 2.05kg, while the X301 is only 1.5kg, and can be taken down to a ridiculous 1.33kg with small battery and no optical drive. This is quite a big difference for notebooks in the same size category.
Temperature: Another advantage to the X301. The MBP seems to run noticeably hotter according to the NBR reviews. Or to be more precise, the aluminum body does a good job of transferring the heat to you.
Looks and design: No sense arguing. Some prefer this, others prefer that. Both laptops are sleek each in their own way.
Heh, I think this summary won't make the decision any easier.
Bottom line, IMO, the decision between a Mac and a PC is far simpler, if you think about the OS you plan to use. Fundamentally, a Mac will function better with MacOS, and a PC is better geared towards working with Windows. If you intend to run Windows, don't get a Mac. Some of the cool features will be wasted, and on the other hand the usability will be diminished (due to factors like keyboard and battery life mentioned above).
Good luck with your decision.
