I disagree. Cheap phones are slow, and trying to scroll through barely-responsive webpages at 10fps gradually frays one's mind. I'd pay a good sum to avoid going back to that again.
...Unfortunately, the phone makers know it, and keep releasing updates that suck away more resources right around the time a newer, faster, more expensive phone is released. Not naming names, but iHate it when companies do that and I wish they'd Think Different.
