Thanks for the idea about the Juno-G!
I decided that no perfect small keyboard existed that had the features I wanted.
I decided that keyboards like the Alesis Micron, Korg R3, or Korg MicroX were not quite what I was looking for (possibly the MicroX was the closest).
I decided that I should buy a regular keyboard with all the features I wanted, but live with the fact that its not portable (a workstation). And, I should buy a portable music making gadget for my "sketchpad". Once I create songs on the sketchpad, I can flesh them out on the keyboard workstation.
On the portable side, I became interested in the Yamaha QY70 or QY100, or the Korg DS-10+ running on a Nintendo DSi, or Rythm8 running on the Sony PlayStationPortable. Possibly the Tenori On would be another alternative, but its not cheap. I played with a couple of iPhone apps I bought like iSyn but I felt too limited and the screen is just a little too small to work with for an extended period. Plus, I use my iPHone for work, and so I cannot set airplane mode to ignore calls, so my iSyn session would get interupted by phone calls. Imagine if your DAW on your computer suddenly dissappeared while you were working on it because a video call was coming through! very annoying.
Eventually, I decided that I wanted a DAW on something more portable and less buggy than a laptop. Because with a laptop, you still have to plug a MIDI Keyboard into it, and you have latency to deal with, unless you also use a USB or Firewire Midi audio interface. I bought an M-Audio FastTrack Pro to use with my Dell XPS M1330. However, this is not too portable. Also, I have Vista, which is super crappy. Worst peice of crap since Windows ME. I just got Win7, and can't wait to get it up and running!
The best solution I could come up with for portability for now, is the Yamaha QY's or the Sony PSP running Rhythm8.
I went with Rhythm8. It was free. I bought a used hacked PSP for $140. (a hacked PSP is required for Rhythm, as its not "official" software for the PSP).
Its essentially a lightweight DAW. I just wish I could plug a mini keyboard into it like the Akai LPK25.
On the non-portable side of things, I bought a used Roland Fantom X7. I wanted aftertouch, and 76 keys, and all of the features that this workstation has (huge arpeggiator, huge sequencer, sampler). It basically has a built in DAW. However, I can plug this keyboard into my FastTrack Pro and run a DAW on my laptop with it as a MIDI keyboard too.
I plan to get a analog synth or analog modeling synth to create sounds with. These created sounds can be loaded into the Fantom, or into Rythm8. I will get either an old 80's synth like a Juno60, or a newer mini analog modeling synth like a Micron or MicroKorg.
