Up to now, it cannot be said that its flagship has been fully developed. However, because of some strategies of Lenovo, the X2x0 series (the core series in the IBM era) that was the most in the way was killed.
Prequel period:
X300/30 1: Businessweek claims to be the most perfect business notebook computer: it started well, but it is more limited by the times and hardware, and it is not so beautiful in the real situation (ultra-thin LED white spots, battery performance, small-capacity SSD, weak ULV processor). It is really the peak of the old ThinkPad design, and the actual situation is not satisfactory.
Originating segment:
20 1 1 This year is actually a difficult node for ThinkPad's flagship transformation. The machine looked like a semi-finished product and didn't sell well in the end.
20 12
The first generation machine itself is very good, and the third generation ULV has average performance. However, compared with X230, which was in full swing in that year, it is still quite poor (it is difficult to choose X 1Carbon 1). The latter has a strong standard voltage of 35W, dual SO-DIMM and fancy accessories (X230 is still active in the second-hand market, and there are magic works, X6538).
X 1Carbon 2 (new X 1C): Lenovo has racked its brains to make a convertible Fn key, but changing everyone's usage habits can be said to be a big death, especially the problem of changing the shell key. The second generation is a very failed generation. So far, when it comes to this machine, there is still a funny voice on the Internet.
X 1c3, the first PCIe-SSD used by the Windows camp, should be a work of redemption. X250, another strongman of the same generation, is also very weak, but the problem of the screen door basically ruined this machine (I dare not say how many sets there are statistically, but I happened to work at ThinkPad on 20 15, and I still have an impression). X250 also has a memory screen door, so there are many posts on the Internet (5 1NB, Reddit, post it). The memory problem of X250 lasted for three and a half generations (X230s should be included), and it was not solved until X270, which is also good luck. In the X 1C3 era, the ThinkPad's machine king was T450s, which can be regarded as the best traditional ultra-portable TP in recent five years.
X 1C4 can be said to be the most successful generation of carbon, but it is not so perfect. Online search: X 1C20 16, with the truth.
X 1C5: The machines still on sale have strong performance. After all, C4 is basically top-notch in design, but C5 is not necessarily in the end. At the time of delisting, some models were recalled because the screws may scratch the battery, which may lead to the risk of fire (the actual situation is more serious than Lenovo said. If you pay attention to the notice, it covers machines that are close to 10 months old, that is, machines that started from their debut. In fact, some of them are problematic. Earlier, another ThinkPad boss mentioned that X 1C5 has 77 screws, which is easy to cause the problem of fineness. Lol, it is better to change it in the future. But other than that, X 1C5 is an excellent machine. (13- 14 inch, except for a Fujitsu U937 in a niche market, there are no obvious competitors of the same kind) (of course, there are many competitors at different levels).
X 1C6, which just went on the market, was troubled by frequency reduction. This generation may repeat the mistakes of T450s. After all, T480s is rare and excellent. Fortunately, another cutting-edge product X280 was killed, and the pressure was a little less. The HDR screen is the biggest highlight.
X 1C7: I don't know how to change it. It can be replaced by all C ports to improve heat dissipation. Who knows, I hope it will get better and better.
To sum up, I don't think this product is so good, especially from the perspective of business notebook computers. (Interface, thin and reliable), only thin and light. (But there are many consumer grades that are light and thin, and there is no advantage. )
As far as ThinkPad in 10 is concerned, if I were to rank it, I would list these series like this.
ThinkPad Ts: The classic era of T400s-T420s, ZTE of T430s and T450s, and T460s-T480s are all the first-class productivity of TP (most of the four distributors that individuals have contacted before are TS). The 25th anniversary edition is based on T470, and T470 network is a tribute to T450s. T25 is also the first commemorative model based on X series design, which is not the highest end. 95 points (few opponents in the same period)
The classic era of ThinkPad X2x0: X200-X220, the most advanced material, and the rare high-quality screen at the same time, are beyond the reach of other series. X230 and X270, the last small steel cannon. The connotation of X280 series has changed, and there is no difference between good and bad. 90 points (there are still corresponding products in the niche market in the same period)
X 1 carbon, personally, the goods are almost fair here. 85 points is still a B grade.
In other series, maybe I will put S in the fourth place, but after all, I don't know enough, so I won't comment. (In my personal circle, the most are Ts and X, only one is S2-20 16, and there is an earlier E430 series. I helped fix a few sets in high school, so I'm not qualified to say it's good or bad.
Logic or something, just look at it without conscience.
