No. IMO they were awful. Sony had Symbian (?) licensed as I recall on some models, and that was the best of it. Moto, HTC, and Blackberry - ugh. My last two pre-iPhone phones (and I've used many in between Androids - every other phone until about 4 years ago) were Treo with a version of PalmOS and it basically froze anytime you looked at it funny, and a Samsung Windows Mobile device. The hardware was decent enough, but Windows Mobile deserved the death it had.

Don't even get me started on the Blackberry devices of the era. Missed the keyboard still though.

Only the G1 (first android) was in iPhone`s class (and may have outclassed iPhone a bit with GPS built in and support for 3g). No one else even got it. It was a complete game changer.

Most of phones you might be thinking is probably post-iPhone. Just couples but I used couple pre-iPhone smartphone OS and oh boy they sucked.

I still remember my HP Ipaq 514. i wouldn't wish it on my worst enemy.

Sorry but none of the offerings were any good I had WindowMobile 4-6 machines, Palms, the Nokia N61 and blackberries they all sucked. The iPhone was 10 years ahead.

The iPhone / 3G / 3GS / 4 were so far ahead of what any of their competitors were doing that it can be difficult to conceptualise it in hindsight.

HTC, Sony, Moto, RIM - there's a reason these companies barely exist in the same form anymore. Samsung were the first to consistently catch-up to Apple - largely because they're official strategy at that point was 'copy Apple'
