    1. According to comparison on lenovo web site X201 does not have Intel Turbo Memory. Does it mean that a slot for Wireless USB is missing as well? In case of Wireless USB absence and existing 3x3 antenna kit, there will 1-2 un-used antenna, right? (2-3 WAN, 2 for WWAN) Could anybody explain to me, what does bold letters mean in 3x3/2x2 UltraConnect II antenna mean (Eg. How many antennas this card need? 11a/b/g/n and WiMAX wireless, PCIe Half Mini Card, Intel Centrino® Advanced-N + WiMAX 6250, 2x2 AGN + 1x2 WiMAX)
    2. Which WAN would you buy, why?
      ThinkPad bgn Wireless
      Intel Centrino Wireless-N 1000 [$0.00]
      Intel Centrino Advanced-N 6200 (2x2 AGN) [add $20.00]
      Intel Centrino Ultimate-N 6300 (3x3 AGN) [add $40.00]
      Intel Centrino Advanced-N + WiMAX 6250 [add $55.00]
    3. It seems to me that WXGA disp. could have 6 antennas, on the other hand WXGA+ only 4 antennas. Is that right? Does webcam reduce number of antennas?
    Thanks

    3x3 means it can use 3 channel for transmitting and 3 channel for receiving.

    2x2 means 2 transmitting channel and 2 receiving channel.
