you obviously havent done much witht he emu yet as its far from trouble free

sound support is really bad atm and even on the fastest pc is stutters like hell no matter the app/game through paula emulation. Just try playing a music mod, it wont sound right at all.
Through ahi is another matter though no probs what so ever, but for normal stuff, its bad news

its bsdsocket emulation is far from perfect, functional but not 100% like it would be on my amiga (ppc equipped).
There are other niggles also but youll come across them over time. And yes i have latest winuae setup with os39,ahi and other os stuff. on a 2.4gig amd rig.
