I'm a huge BlackBerry fan and love my Bold 9930 and my Playbook but man, I just can't recommend a Tour. I'm sorry if I offend someone but that device is not a device that is competitive with anything out there today.
Before the OS7 devices came out, I never recommended BlackBerry, even though I had one myself. However, since the Torch1 came out and especially since the OS7 devices came out, that is all I recommend to my friends.
If budgetary considerations are an issue I would suggest the Torch2, now that is an awesome phone and it is a screaming good deal at $49.99. By the way, I saw, and posted, a display at Target in Portland Oregon for 29.99. Also the Torch 9850 has a beautiful 3.7" screen and is on sale at Verizon for about 99 bucks.
Bottom line, I don't think the Tour will best serve you today. Even the new, entry level Curves with OS7, are clocking far above that with their 800Mhz processors and you can still buy a Torch 1 with 640Mhz for 1 penny.
Lastly, the OS7 phones, Playbook and future BB-X phones are in line to benefit from the awesome tools BlackBerry is providing developers using HTML5 and I don't believe the Tour will benefit from this though I'm not 100% certain on this issue.
