I was a Blackberry user forever but I had been reading up on the Android platform so when the HTC EVos came out and I could find one, I switched to the Android side and it is like night and day comparing it to any other phone I've had. The Blackberry and the internet were not a combination that made for an enjoyable experience.
I have cable internet service and have a Wi-Fi network set up at home. The Evo accessing the cable service through the Wi-Fi is faster than I would have thought possible. This speed along with the phone and the great screen makes it easy and enjoyable to access the internet with the Evo if I'm not around the main desktop PC. Even when away from Wi-Fi the Evo still has enough speed and capabilities that surfing the web is totally feasible and enjoyable even though it's normally only a 3G hookup. You'd be surprised how many places there are that you can access a free Wi-Fi source just about anywhere you go.
No phone can totally compare to a good ISP and a big screen display for your desktop PC but the Evo is the next best thing as far as I'm concerned. It's kind of like having Len's living room on my belt or in my pocket.
