- Viewsonic Viewpad 10
- Dell Inspiron Mini Duo
- Samsung Q1U
- Viliv S5

Check them out, download a build and try it for yourself, read their forums and see what is presently happening, from the SurfacePRO 3 work in progress to the older Asus T100 ongoing work and many other PC's, Laptop, 2-in-1's, the older Surface 2, Dell XPS 12, Dell Venue 8, HP Stream, Sony Viao and many others. AOSP KitKat is their present released product, Lollipop version 5.1.1 is their present development cycle. There are builds available for either.
Con A bit ugly
Using puppy makes you feel like you just jumped 20 years into the past. Being that the purpose of Puppy Linux is to run or really low resource machines the software used is often on the older side, which is precisely why it has a 20 year old look.

Con Not as light as it used to be
It's light, but not as light as it was 1-2 years ago.
Con Smallest software library ever
You can barely find any precompiled packages for Puppy.
Con No built in compositing
Being a low resource distro there is zero built in compositing for the JWM window manager. Though one can be added through a bit of work.
