Getting ready to but 13 MBA 13" with 256SSD. I want to partition the drive via Bootcamp to the smallest practical MAC partition leaving the largest amount for Win 7 Pro. I will be using the MS Office Suite, CS5 and Quickbooks Pro. My questions are does Lion work well with Bootcamp and run Win7 Pro with the performance I need. Are there any issues I should know about? Also can I use a portable DVD USB drive from my Lenovo instead of getting the Apple drive? Any help or advice.
