All depends on what CPU and when this rumored Lenovo lappy appears. Tech features on it says 2Ghz LV Merom/Santa Rosa, 3 USB ports, but no FW, just like the MBA . I'll bet it costs a lot more than a MBA with a standard SSD, 4GB RAM capability with 2 Dimm slots. A new CPU coming in May, according to digitimes link below? Will the MBA be updated by then, with these new CPU's in 22mm die size? http://126.96.36.199/search?q=cach...ontevina+CPUs+in+May&hl=en&ct=clnk&cd=1&gl=us But all of the "x300" stats seem to make it a much higher performer than the MBA, and it's got that wicked 'nipple' thingy, lol. http://www.electronista.com/articles/08/01/19/lenovo.x300.leak/ http://gizmodo.com/346797/ultralight-lenovo-x300-series-thinkpad-leaked "integrated DVD burner"? Would make it thicker, but you do get a 1400x900 screen.
