I want to relate to you my experiences as a recent reverse switcher. For the past couple of years I've been content to let my primary home computer be the laptop I get from work. Previously that was a 15" PowerBook, but recently I changed jobs and got a Dell laptop (see signature). After two weeks of using the Dell I have to say the PowerBook was the zippier computer. People that say that Windows XP is zippier than OS X must be using Windows on a 3GHz or higher Pentium 4, I guess. On my 1.6 GHz Pentium M, Windows XP is NOT more responsive than what I was used to on my 1.5GHz PowerBook. For all of people's bitching about the Finder, I find Windows Explorer to be more sluggish. And Windows XP overall seems to be more sluggish, especially at multitasking. If I have one CPU-intensive task running (e.g. copying files from DVD), the whole system grinds to a halt. Granted, my PowerBook had 2GB of RAM, but even my old 1GHZ iBook with 768MB RAM was better at multitasking than my current Dell. So then I thought to myself: well of course the Dell is slower, it must be a $1000 "value" laptop. Wrong. I go on the Dell website and find out the Dell D600 is actually comparable a 15" PowerBook. The base configuration is about $1800, but once you add 512MB, an 80GB hard drive, and a combo drive (all of which I consider essential features, not "bells and whistles"), the price goes up to $1950, about the same as the base configuration 15" PowerBook which includes those essential features standard. Add a Bluetooth module to the Dell and the price goes up to $1989, nearly identical to the $1999 price of the PBook. I can do without the Bluetooth for now, since my Sony Ericsson phone syncs over infrared (which the Dell includes), but in the future Bluetooth is going to become the standard for synching phones. The only advantages I saw for the Dell were these: - Seems to be about a pound lighter (but then again only 14" screen) - Longer battery life (just under 4 hours as opposed to just over 3 hrs for PBook) - Much stronger Wi-Fi reception - Ran far cooler than PBook, which tends to really heat up - Slightly higher resolution: 1400x1050 vs. 1280x854 for PBook But for day-to-day productivity my PowerBook was simply better. I could run Microsoft Office and my Java development tools (primarily Eclipse) without a hiccup. My assessment is that Apple's G4-based laptops are currently outclassing the competition's Pentium-M based laptops.
