We've had the Sidekick II for about two months. Although my 11-year-old likes it for its buttons and Gee Whiz value, I find it very awkward to use as a phone. It doesn't have a normal keyboard, so you must flip the screen up to press the keys, then flip the screen back down to listen and talk. When you get into a voicemail situation, you have to keep flipping the screen up to "press 1 for English", etc. Very annoying.You also must pay an additional $20 per month if you want to browse the Internet, use Instant Messaging, or even Download Fun. Otherwise, all you get is phone calls and text messaging (which is also extra). Even the non-sidekick phones let you get T-Zones for Instant Messaging as a $5.00 option.Another gripe is that the phone is falling apart after two months of not very rough usage. The screen no longer slips into place when flipped open and the letter "A" has fallen out. It occasionally just freezes for no reason. The first phone I received froze up the first day and had to be replaced.The battery is built into the phone, so you can't take it out to let the phone reset itself. No such thing as having an extra battery on a trip, for example.Internet browsing is cool, but so slow you think it stopped working. I think some of the fault is just the slow connection, but the other part of the fault is that the phone seems to take a long time to actually build the web page it's trying to display.Oh, yeah. Another problem is that T-Mobile expects you to pay $9.95 to set up your album on its web site, then 29 cents for each photo you upload to it.The phone is too large and heavy and has poor quality voice reproduction. You can't use wallpaper and the ring tones sound terrible.Although it looks good on paper, it isn't really ready for prime time.
