I shelled out the $149 last night, but was not able to successfully download my 1.2 GB purchase.  In my experience, mega-downloads through http links inevitably get stalled.  Sometimes I can use a utility (GetRight, for the PC) to complete the job.  Oddly however, Xfrog's file server cannot resume broken downloads.  I am still waiting to hear back from Xfrog for a solution.  If any of you folks have ideas on this, feel free to chime in!
