T Mobile USB stick user here and it is, in my opinion, completely pointless.
I'm actually wondering if there's something wrong with the USB stick or the way I have it installed and set up on my laptop, it's that slow.
Google takes about 1 minute to load up and it's hardly a "content rich" web page.
This is on GPRS as there are only a few places local to me that I can get a 3G signal. On GPRS it downloads, according to the download manager software thingy, at about 3-4 kbps ( if I'm lucky!! ). I've never had an HSDPA signal so I've no idea what it's like on that.
I find this bizarre because if I hook my Vario II mobile phone up to my laptop and use it as a USB modem in the same area, it happily loads pages up and downloads at well over dialup speed which is perfectly useable for web browsing.
Not impressed with the T Mobile USB stick so far to be honest. It's the latest version I have as well, the Huawei USB stick (dubbed web’n'walk Stick III).
And the other annoying thing is the low quality image rendering, but I think a lot of mobile internet access doohickeys have this issue.
