1) Will Pyra ever be able to emulate Nintendo 3DS or Playstation 2? I know this is a bit childish but theoritically GPD Win should be able to emulate both of these. I don't know how well they will do, but they might work.
I don't think there'll be a 3DS emulator out for any system, so that's something no one can answer whether it will be possible on any system.
The initial Pyra will not be able to emulate PS2, but who knows what future CPU upgrades will bring
The GPD Win will also not able to properly emulate PS2.
Well, theoretically, it can run PCSX2.
My PC at home (with a Core i7-3770 @ 3.40GHz) works okayish with most games, but still has some slowdowns with some games. The passmark value for that is 9340.
The passmark value for GPD Wins CPU is 1711, so it's about 4 times slower.
So most games will probably not run playable (or: enjoyable).
2) Emulating light Windows apps? I mean will it be powerful enough to run not graphically demanding apps without much slow-downs?
The Pyra? Yes, with ExaGear and Wine, it already quite some Windows games (tested on the devboard).
Sure, for Windows games, the GPD Win will be better, but stuff like Diablo 2, World of Goo, etc. will run fine on the Pyra as well.
3) What will be the final price? Ok, there are a lot of threads about this and most say it probably will be about $500 but what do you guys think.
Will probably be announced within the next few weeks.
The retail price will not be that much different from GPD Wins retail price.
4) Is it the right decision for me... I mean the thread about GPD Win was able to convince me about buying a Pyra but do you think it is the perfect device for school work, pentesting, emulating-gaming,learning, coding and daily stuff?
Hmm, hard to tell. It depends what is most important for you.
For daily stuff, both systems will be good. Websurfing, emailing, office, etc. will run without any issues on both systems.
Coding... well, depends on what you want to code. If you want something like VisualC++, then a Windows system is probably better.
But that's something devs can probably tell about, I'm just porting some games, and I clearly prefer Linux systems here.
Emulating / Gaming.
As mentioned, the GPD Win will let you play a lot of Windows games. How well they will run on the system is unknown.
More recent games are probably too demanding for the system, strategy games often have small icons and text so it might be unreadable or the capacitive screen will be too inaccurate (it's hard pressing small buttons with your fingers). Pyra's resistive screen will be better here.
For example, I would not play FreeCiv on the GPD Win, but I already play it fine on my Pandora.
What I like is that the games on the Pyra will be especially ported to run on the system.
So you can download stuff from the Repo and it will run fine out of the box. I always loved that about these systems (GP32, GP2X, Pandora, etc.).
Install and play.
With the GPD Win, you get a HUGE library of games (all Windows games), but need to install most of them first (can take a long time) and then configure them (resolution, controls, graphics settings).
If you're unlucky, the game is too demanding for the system or it isn't enjoyable for some other reason - and then you have to uninstall it again.
This is too annoying for me, but that's my personal taste.
When I want to play a game, I don't want to wait and setup everything first, I just want to play and know upfront it works fine.
So a huge library of games can be good, but it can also be a downside as all these games are designed to run on any Windows system and are not customized for the GPD Win.
Whereas the Pyra will have a smaller library of games (though you can probably play many classic Windows games as well), but the games you will have will install almost instantly (depending on the download size), can be removed within a second and they are preconfigured.
