John Gruber:

I think the Pre stands a much stronger chance of stealing customers away from RIM than from Apple. For as good as the Pre is, and I’m convinced it is excellent, it just doesn’t have much to offer that would sway someone considering an iPhone [...] The Pre is the BlackBerry Bold done right.

I tend to agree about him and especially regarding keyboard. A software keyboard is a non-issue for someone who has never used a smartphone before which is 90% of people.

John also quoted a passage of Jason Chen’s Pre review for Gizmodo; who has experienced some glitches while running multiple apps at the same time on the Pre,

He is praising the Pre’s multitasking support and interface. But these exact words also summarize perfectly why Apple has withheld multitasking from third-party iPhone applications. The Pre will let you run too many apps at the same time and suffer the consequences. The iPhone will not.
