Some dreams come true...
In the mid 1990s I had a fantasy about an actual physical real scientific calculator that computed to over 30 decimal places...It finally came true with the DM42.

The WP 34S has done this for a while too.

In the mid 1990's, you say? Your dream came true in 1994. The HP 48/49/50 have been able to do that and far more (settable up to 9999 digits!), with the LongFloat library installed, first published in 1994. The HP48 version was fast, but the 50g version is even faster: square root of 153 to 100 digits in less than 0.3 seconds. "Get serious about precision. Get LongFloat." X<> c Joe

RE: Some dreams come true...
I think mathematica can run on most of the new smartphones. The point is if someone wants to port such work on a smartphone.
Most of the time the possibility is there, what is missing is the manpower working on it. Plus what I saw often is that people overestimate always the role of the tangible things (hardware), over the work required for intangible things (software). Developing proper libraries needs a lot of time, while many think it is a work of a couple of days. Wikis are great, Contribute :)

RE: Some dreams come true...
Mathematica needs a proper keyboard to be used at its maximum, otherwise there are things such as WolframAlpha for the more casual use with a smartphone.
I'd say that my earlier convertible laptop / tablet with Windows on it was the closest thing to a portable device capable of running Mathematica. You might find smaller devices on chinese sites which run Windows and are as small as you can get. They will technically run Mathematica but I doubt about their actual practicality as a work machine.
