Oh, I'd be very interested in getting one when they come out, if the specs are decent and the teased features actually pan out. I upgrade systems about ever 18 months, so if it's not out until next year there is no sense in waiting; if it's that good, I'll upgrade early. If not, I'll compare it to what Dell has later in the year when my next system hits the 18 month mark.

They also haven't released enough specs to be certain; the polls suggest it's going to be a relatively powerful 14" machine, but since nothing is official yet...

As for me, the T420 wasn't powerful enough to be really comfortable for my professional use even when new; the quad-core machines of that generation were the first laptops which had sufficiently caught up with desktops to be attractive as a primary machine, well, pretty much since CPUs started being measured in 100s of MHz rather than 10s. Lenovo chose not to offer any quad core options in a 14" model; Dell did (and then they swapped for Haswell, and now are both offering it for Skylake.)

Also, the T420 already (unfortunately) went to a 16:9 rather than 16:10 screen -- as did everything else of that generation I'm aware of except for Macs. Various companies have started experimenting with 3:2 screens on their hybrid tablets [and the Chromebook Pixel], and I really hope this catches on more broadly on full-size laptops, as it seems like a really good happy medium between 16:9 and 4:3.

If it's not powerful enough to do real work or play games on -- both of which require something pretty close to the latest and greatest -- I've still got an X201 which is fast enough for everything else... has a superb keyboard, 16:10 screen, and while it's ridiculously heavy for a machine that compact with the 9-cell battery, pretty close to all-day battery life even after nearly 6 years.
