I'm new to this forum, but maybe I can add some info for you.
I received my VGN-A117S last week. Since I'm living in germany I ordered in Germany.
per default it has:
1,7 GHz CPU, 80GB HDD, 512 MB RAM (PC2700 from Infineon), ATI Radeon 9700 with 64 MB-RAM. Bluetooth, wireless (802.11 b/g), firewire (4 pin), 1 pcmcia slot, memory stick slot. 3 USB (2.0) VGA out(analog), av out, LAN (1 GBit), DVD +- burner.
Overall impression is very good. The quality is high, the display is so good I never saw something like that.
The system runs fine with 2 GByte RAM PC2700 (Kingston, or swissbit) eveb though Sony say 1 GB max. But I would never buy it again with this slow 80 GB drive. I'M currently looking on how to change it. There is nothing in documentation like it is on how to change the memory.
I installed WIndows XP Pro on the machine and I must say that the performance is really great.
Hope I could help a little bit!
