I recently bought a mac book air with Lion after my 3rd problem with the screen on my work provided Lenovo (T410s). I've been using VMWare Fusion to develop. For the most part, I've been really loving it. The performance is pretty good, and it's nice to have osx for my non .net stuff. However there are a few areas I ran into problems. First I found I had to disable hardware acceleration in order to get WPF controls work. This has impacted rendering performance more than i'd wish. Second, and more painful, I've had issues with USB devices working (again a problem with the VM). For the most part I can work around these issues, but the work arounds have impacted me in undesired ways (for instance the application i'm working on requires a dongle for security, i've been working around it by leaving a hack in the code... but once I accidentally checked it in..). Finally, and probably my most petty (but most frustrating issue) is there is no home/end key (though i did find fn left and fn right work)
