Please post your fab full screen video method. 
I like your idea on cutting down the file size of each song.
The past few months, I've been doing the exact opposite though.
Instead, I've been upgrading all of my 128kps music by ripping them again at 320kbs.

mp3->wav->mp3? yuck, how about just use FLAC on the original source

...tons of music @128kbit "quality"? "Funniest" (or saddest) thing i've read today. Especially with 32GB cards.
That post is a witness why the web in 2013 still won't get rid of so called quality.
F*ck file size: the loss of bandwidth too often coupled with decoder/high-frequencies ringing doesn't compensate. Even in 2004 i preferred at least 192kBit MP3s on my SX1, and that thing had a mere 512MB MMC. What are desktops /harddisks for? Storage!

If you are unable to hear a difference between at least 128 and 256, you should go see a specialist. Seriously. Maybe over the last 30 years you were living with f*cked-up hearing without noticing; building instruments isn't proof of the opposite. I mean, also Beethoven was deaf and so on. Referring to some pages on the web won't help you with that. My hearing is more than ok, i have the test printouts from this month here in my table, as i took the opportunity during a scheduled visit.

Anyway. None of the Nokia Internet Tablets supports mp3pro, so you're just wasting time/money in encoding with that format. A non-mp3pro compatible player will only "see" the mp3-standard part.
From http://www.mp3licensing.com/mp3/mp3pro2.html:
And as @don_falcone says, space is not a factor anymore. For something like a N900 you want hardware decoding and/or low CPU usage.
From http://www.mp3licensing.com/mp3/mp3pro2.html:
How will mp3PRO content play on mp3 players?
The mp3PRO technology is a dual-rate system. The backwards compatible mp3 audio bit stream is run at half the sampling rate than the enhancement, thus to be able to generate mp3PRO bit streams the digital audio input data must be sampled at 32 kHz or above (44.1 or 48 kHz recommended).
That means:
mp3PRO content played on an mp3PRO decoder will have sampling frequencies of 32 kHz, 44.1 kHz or 48 kHz.
The same mp3PRO content played on an mp3 decoder will result in sampling frequencies of 16 kHz, 22.05 kHz or 24 kHz.
The number of channels will not change whether such mp3PRO content is played on an mp3PRO system or on an mp3 system, in case of "mono" and "stereo" content.
In addition to the "mono" and "stereo" formats, the mp3PRO format adds the so called Low-Complexity Stereo ("LC Stereo") technique to the plain mp3 format:
Mono mp3 content can be enhanced not only by applying the usual PRO enhancement for higher audio bandwidth, creating monoaural mp3PRO content, but also by LC stereo to make it a stereo channel mp3PRO bit stream.
This feature is designed to allow stereo coding even at extremely low bit rates. A plain mp3 decoder however would play LC stereo enhanced mp3PRO bit streams as mono.
That means (for LC stereo encoded mp3PRO content):
LC stereo encoded mp3PRO content will play as "stereo" on an mp3PRO system (at sampling frequencies of 32 kHz, 44.1 kHz or 48 kHz).
The same LC stereo encoded mp3PRO content will play as "mono" on an mp3 system (at sampling frequencies of 16 kHz, 22.05 kHz or 24 kHz).

while interesting, i would hesitate to call that experiment a scientific study.
there were no controls and far too many variables {sound equipment, test data, sample selection, sample size}.
however, there are studies that also suggest that perceived audio quality is not directly correlated with data rates. most people cant tell the difference between average and high data rates. however, studies {including the one you posted} also suggest that a non-trivial portion of people who care about it can do much better than average.
the moral of the story is to use ogg vorbis at quality 5 and get better perceived quality, a smaller file size, and a codec unencumbered by patents or commercial ill will.

The reason why I stopped using 128 kbs, is probably more psychological than anything else.
Having a bit rate that low somehow began to feel "dirty" to me.
I guess it's a little silly of me to only have 320 kbps songs now because I've also heard of similar studies.
Anyway, my video settings probably tops anyone else using an older, Maemo 4 tablet.
For normal videos and movies:
640x360
.avi (Xvid)
25 fps
900 bit rate
44,100 hertz
128 kbps
For cartoons:
720X480
.avi (Xvid)
15 fps
900 bit rate
22,050 hertz
128 kbps
Both need to be used with Mplayer, the stock Media Player can't handle them.
It's also wise to shut down all apps and go into flight mode.
Also, try this for a YouTube video:
Find one that has 360p (.mp4).
Go here:
http://www.clipconverter.cc
Select .avi (Xvid) and crank it up to 768 kbps.
Continue.
Save.
Download.
Play it on Mplayer with everything else closed down.
Not too bad looking on a 6 year old tablet.

it's not the fact that 128kbps is horrible.. (it actually is)... it's transcoding that will ruin everything beyond what you imagine.
I used to not care about the quality... until one day i decided to go FLAC and compare... It was a whole new song!
So, I only have FLACs on my phone (might be overkill, sure, but I can't bother converting them to mp3 320kbps) and MP3 320kbps when FLAC is not possible, nothing lower.
You'll obviously won't notice much difference / none at all with the stock earbuds that come from most devices.
The difference IS there and i'm partially deaf since I was born. So all of you who have good ears, stop making me sad and go get proper music.
The day someone figures out how to steal someone else's good ears and put them on another person, will be the day half of the internet gets deaf. Mwahahahah

I have a few .flac songs, and yeah, I'm pretty sure I can hear the difference.
Up to 50 megs on one file though is a bit too much as I've got about 45,000 songs.
Also, the time slider doesn't work in Xmms playing .flac files.
