In the performance stakes the use of the intermediate low-voltage processor means the X200t outperforms most ultra-portables. Indeed in PC Mark Vantage the X200t was 46 per cent faster overall than the Latitude XT; hampered as it was by a slower CPU and a slower hard drive. This trend was continued in our in-house testing, where the X200t remained almost identically faster than the Latitude XT.
This, you'll probably agree, is a significant difference and one you're bound to notice in general operation. However, battery life on the two is more or less identical. In fact, in the lower intensity Reader test both registered exactly three hours and eight minutes, while in the Productivity test the X200t managed just less than three hours. Neither of these results is great compared to dedicated ultra-portables, but an eight-cell battery is available separately and should offer exactly double the battery life should you need it.
More importantly, though, there's no aspect of the X200t's raw performance that is bested by the Latitude XT. This isn't to say that the XT doesn't have some advantages over the X200t; it is slimmer, lighter and arguably more stylish than the ThinkPad. However, it's also more expensive for a comparable specification and while the screen on the Latitude XT is definitely superior, aside from its reliance on a digitiser pen the Lenovo's screen is very good.
We're also more convinced by the X200t's durability, largely due its slightly more industrial feel compared to the brushed metal niceties of the XT. Fundamentally, though the XT has many qualities, the ThinkPad seems a slightly more comprehensive solution if a Tablet PC is an absolute must.
Lenovo once again delivers an excellent ThinkPad that addresses its core audience very well. Its lack of a finger friendly screen might hamper it somewhat in the long run and battery life out of the box could be better, but aside from these issues it's a fine effort.
