I did some math, and worked out that, basically, if I want an iPod touch for all my music (not counting movies, podcasts, photos, applications, and other content), I require a 64GB or larger iPod touch... I'm definitely interested in one (and I have zero interest in an iPhone). Executive summary of the math I did: Size of library (100% Apple Lossless): 85.52 GB Total Time: 11 days 23 hours 30 minutes 36 seconds Estimated size after conversion to 160 kbps MP3: 28.51 GB Usable space on 32 GB iPod touch (not including space used by OS): 29.80 GB Usable space on 32 GB iPod touch, using 5% OS size estimate: 28.31 GB Therefore, I'll be short about 200 MB, if my math is reasonable, of fitting my entire library on an iPod touch 32 GB... that's including only the song files. I also have about 220 MB worth of movies, and 60 MB of photos. EDIT: Thanks to the people who replied... I've edited the thread title, to reflect my change in purchasing decision. Looks like, if I use 128 kbps (or lower) AAC, it WILL fit on a 32 GB touch, with space left over.
