Lenovo just started shipping the Y560s and I got in on the last hour of pre-order discounts. $400 off for an even $999.
I plan 8GB later but SSD are power hogs. The 7200rpm drive is fast enough. But my desktop is getting a 128GB SSD today to replace the 300GB Rapter that died. Western Digital is taking forever to ship the replacement but once I get the it my storage configuration will be "C" 128GB SSD, "D" will be the 300GB Rapter and will hold the swap files and one space hog of an app. "E" Will be my 2.7TB HW RAID5 (4x WD "Black") array where I keep my data.
