Following this thread. I had my full size 16 inch screen laptop with a buffalo SNES USB controller in the bed last night as I winded down. Playing some Mario Bros 3.

. More portable than the Virtual Boy! I need to get something a bit smaller.
I was recently considering a PSP also, but decided to go Android or with a smaller laptop. I do really dig how the PSP can run .isos of PSP & PS1 games as mentioned though.
I'm a
big android fan but I like the idea that I can also use a small Windows laptop for other retro related softmod projects, moving ROM files to SD flash carts, DLing and unzipping full ROM sets, organizing my ROM/.iso archive, FTPing files to modded consoles, etc, etc. I think I want a "this is my retro emulation and retro tinkering laptop" machine, but I still want it relatively portable for emulation on the go.
For $50 I'm still open to the Android route as a dedicated portable device. This would also give me access to the Google Play games which is a plus. I'd have to use a bluetooth controller which does make all these options a bit less portable. I also won't do it on my main phone. I hate playing a game and getting a phone call. It would be a secondary device.
I have been eyeing this 11 inch Windows 10 laptop (or something similar) as a recommendation from another community member:

Of course you'd be fine from 2600 through 16 bit CD consoles which would be my main focus. It supports bluetooth & USB controllers. With only 32GB of flash storage, I'd be loading selecting ROMs I am playing at that time on the machine and keeping my USB drive close by.
@Sarge, you mentioned PSTV. There are some cheap Andorid TV boxes running Retro Arc well out there. I like the idea of one tiny box with a pre-installed GUI for YouTube, Netflix, .MKV movie playback, and retro emulators. This is a project I might eventually get into. I'm leaning more towards this than a Retro Pi.
