A novice macuser here, but loving it, shame I have to still use Windows, but have to for work purposes, (am a Financial advisor in the UK and all relevent software is written for Windows) I own both an iMac and Macbook Air (1.8, 80GB), and run Vista Ultimate on Bootcamp on both. I wonder why Aero works as it should on the Macbook Air but not on my imac (latest version 20" 2.4GHz) particularly as the specs for the imac are that much higher ?, is it a graphics card issue ? Vista runs very well indeed and have to say that for all its pitfalls which I know there are many issues, I feel personally it is a better experience than using xp. Re: the hard drive I opted for the 80GB Pata drive which works very well, I have alot of data for work purposes but use encrypted USB flash drives (Corsair 16 GB and 32GB Flash Voyager models) which work very efficiently and very quick without time lag. My bootcamp drive is 36GB with about 15GB free. I wonder if a larger hardrive becomes available whether it would be possible to change ? just to be minimalist really so I can do without the USB drives. I would like to that everyone who subscribes to this forum as it is incredibly useful and is making my switch a that much easier and better experience.
