This week, I received my new company-issued laptop.

My company was wise enough to see that the price/performance/reliability debate is won handily by Apple these days, so after years of using ThinkPads [thinkpadx40issues, thinkpadlenovoupdates, thinkpadreference, thinkpadx40], I'm now using the hard drive version of the MacBook Air.
I haven't used a Mac since the System 7 days, so I'm still getting familiar with the machine and system. I'm trying to "go native" with OS/X, and not dual-boot Windows. However, we're a Windows shop at work (see notes about Linux on the ThinkPad [thinkpadx40issues, thinkpadx40], so I'm using Remote Desktop a lot. I also plan to install Parallels VM. We'll see how it goes.
So far, I'm really impressed.
