Just following up on this now. For the time being, I decided to upgrade my Telus plan to a $45+HST "loyalty" offer with 1GB of monthly data included, and $0.05/MB for overages. I expect that to be enough for what I have in mind.

(The plan also includes zillions of voice minutes, enough long-distance credit to more than handle my call volume, unlimited texting (finally), voicemail, callerID display, etc..).

Mobilicity is also having a "sale" right now: their most expensive ($55) "unlimited everything" plan is only $30+HST monthly for the next 12 months for new sign-ups. I'd have grabbed that instead if I didn't still have 2 months to go on my existing Telus contract.

Now back to the Nexus 7 Lovefest!

Cheers
