Hi all, I am a new user to the forums here and I am not a tech heavy person so I'm looking for a bit of advice. I am currently using a Ibook g4 1.42ghz machine. I am looking to upgrade and am looking through my options. I guess I am looking to owners to answer a few questions. First, here are my computing habits: internet browsing, occasional video via hd streaming, hulu, youtube, word processing stuff like word and excell, and itunes for music, podcasts, occasional video. My optical drive has been broken for 2 years on the Ibook and I never got it fixed and don't miss it at all except for the occasional cd rip into itunes. I am looking at a Rev 1 MBA on sale or a Alum MB. The new rev 2 MBA also is intriguing but a bit more than I wanted to spend. Most of my computer time is spent simply browsing forums, watching movie trailers, and word docs. Will the rev1 MBA be sufficient for this. I have been to the Apple store and played around with all these computers a lot. I have noticed that the rev1 on my instore tests seems to stutter with fullscreen HD video, is this always a problem. I do not game at all so is the new graphics on the new MB and Air really a big leap from the rev1 air. I love the size and screen of the air but not the extra leap in cash for the new rev and the new MB is great except I don't really like the glass. One other thing I need the backlit keys as I do a lot of typing at night and would like this feature. HD space is not an issue ( still have 10 gigs free on my 60 gb ibook) so 80 gb would work but is 1.6 ghz processor gonna be ok for my workload for say the next 2 years or is this machine gonna feel slow. I am sure it will be faster than my ibook. Any help here or suggestions from owners of these machines would be great!
