I am going to be playing a live set, in the next few weeks, and I needed a laptop that would run Ableton decently.. I don't feel like taking my work station PC, cause that is to much of a hassle.. I was looking around on craigslist and found these:
"2 GHz Pentium® 4 or Celeron® compatible CPU or faster (multicore CPU recommended), 2 GB RAM (4 GB recommended on Windows Vista and Windows 7), Windows XP (home or Pro), Windows Vista or Windows 7, sound card (ASIO driver support recommended), DVD-ROM drive, QuickTime recommended"
That is the recommended specs for Ableton Live 8, so whatever laptop meets those specs will be fine. After looking at both your links, I find it disturbing that neither of them list the computer specs, therefore I am unable to say whether or not they will be suitable for your needs.
