It looks like TechTV likes the iMac more than the Gateway Profile4. They give the Profile4 an edge on bigger hard drive, it being able to run Windoze and a slightly cheaper price tag in the low-end models.
Who’s going to really need a friggin’ 120GB hard drive though? The only people who are really going to need it are people who are into video and making DVDs, but the Profile4 sucks BIG time in that department. No DVD burner, iDVD or iMovie. So what’s the advantage of having 40GB more? It’s just wasted space. And if you’re really serious into video, you wouldn’t even be looking at either computer.
