I tend to, especially when it comes to electronics, but there are a few things where I just haven't decided which brand to lock in to. One major category is cell phones. I've dealt with a medley of carriers and phone manufacturers, and I'm never sure which is the best. I'm making some switches in this category, and I'm on T-Mobile and Motorola, but I'm not sure if I'm ready to lock in two years with them. For computing, I trust Apple. For cameras, I trust Canon. For camcorders, I trust Sony. I used to buy Canons, but I've been very impressed with the Zeiss lens on the Sonys. For groceries, I trust Safeway. For air travel, I use United, but don't necessarily trust them. They're just convenient because they have a hub here in Denver, but that's about it. Their legroom statements about them having more legroom than any other airline is a joke. For hotels, I trust Starwood. We used to have a ton of Hilton HHonors points, but Hiltons have just become run down in recent years. For cars, I trust Jeeps. Always classic. What brands do you trust?
