Well, it's hard to use DAW without a computer :-), but - Reaper. Small to install, updated constantly, not expensive and price gives you current + next major version, highly customizable with lost of "javascript" addons. Recommended source: YouTube "Reaper blog" (independent) and reaper.fm.

Anyway, as for real synths, I recently tried to sell everything because it was just a silly dream and it's time to give up (Yamaha SY99, Kurzweil PC3LE6, Korg MicroX, Korg Microsampler, Kawai K4r, DSI Mopho, Roland System-1, Roland D-05, Ableton Push) but as with some previous experiences (selling Xbox, I didn't use it) it's just terrible, so many stupid responses and nothing comes out of it. Maybe I'll donate them for free later. :-)
