Dear all the gurus in the mac rumor forums! I am debating whether to buy a facinating new mac book air (11") or wait for 2nd generation ipad. I would need to use it only when I travel for conferences or seminars (yes, those academic types... ) so I use about once a month (a couple of days per month). so the usual suspects: email, internet, word, powerpoint. currently, I carry a samsung netbook, which suits my need, but slow. I have powerful enough machines at home and office, so I don't really need powerful ones. I am getting more interested in using "keynote" rather than MS powerpoint, and that is why I am hooked on macbook air. But the rumor has 2nd generation i pad will somehow enable us to use "keynote" with it. so should I buy macbook air now? or should I wait about a year or less to see 2nd g ipad? Thanks!!
